New Alloy Help site πŸ“–

We're pleased to announce that Alloy Help has received a beautiful makeover this week 💄.

The website has been rebuilt from the ground up to be bigger, bolder and easier to navigate.

Content now appears larger and fills more of the screen, making it clearer and more comfortable to read. The left sidebar can group articles more effectively for better browsing. A handy Table of Contents appears on the right, which displays an outline of the current article and your position in it, and lets you jump to a particular heading.

There's even a Dark Mode for some gentle night-time viewing 🌙.

This forms part of ongoing work to improve the quality and readability of Alloy's documentation, so you can find and absorb information when you need it.

To check it out, visit help.alloyapp.io or select the bottom-right ? icon in Alloy.


Manual Workflow Parameters πŸ› οΈ

Overview

With the April 2023 update comes the ability to specify parameters for manual workflows, enabling the workflow to take input from the user that triggers it!

This new feature is currently only available in the Alloy API but will appear in Alloy Web soon (look out for it in upcoming release notes 👀).

Start by creating a design with the desired parameters represented as attributes. When you create the workflow, you can now specify your parameter design in the trigger model. You can then reference the parameters by their attribute codes when configuring the workflow's actions.

When you trigger the workflow, you can specify which parameters to use and supply any required values. Once the feature comes to Alloy Web, users will be prompted to enter values for all parameters defined by the parameter design when they trigger the workflow.

Parameters greatly increase the flexibility of workflows, to the point where a single workflow can now cater for multiple circumstances that previously required setting up multiple workflows. We look forward to seeing how you use them!

Who is affected?

This change provides new opportunities for workflow editors when designing and implementing manual workflows via the Alloy API.

Details

Here are the steps for setting up a manual workflow that takes parameters via the Alloy API.

Create a parameter design

  • Create a design that implements the designInterfaces_workflowManualTrigger interface.
  • Add an attribute for each parameter you plan to use.

Create a workflow

  • Create a workflow via the /api/workflow endpoint (Swagger/ReDoc).
  • For the trigger property, specify a WorkflowTriggerWebModelBase with a discriminator of ManualTrigger
  • For the parametersDesignCode property, enter the code of your parameter design.

Use a parameter in an action

  • Add an action via the /api/workflow/{code}/action endpoint (Swagger/ReDoc).
  • For the parameters property, specify an array containing at least one object with a discriminator of WorkflowComputedItemAttributeWebModel.
  • For the value property of the WorkflowComputedItemAttributeWebModel object, specify an object with a discriminator of WorkflowSyntaxNodeTriggerParameterWebModel.
  • For the parameterCode property of the WorkflowSyntaxNodeTriggerParameterWebModel object, specify the relevant attributeCode from your parameter design.

Trigger the workflow

  • Run the workflow via the /api/workflow/{code}/manual-run endpoint (Swagger/ReDoc).
  • For the triggerParameters property, specify the relevant attribute code from your parameter design and optionally provide a value.

Street Manager v4 Support 🚧

Overview

For those of you using Alloy to interact with the government's Street Manager service, an important transition is coming up.

In May 2022, the Department of Transport released v4.0 of the Street Manager API. Since then, they've continued to maintain endpoints for both v3 and v4.

While v3 isn't being decommissioned until May/June 2023, the legislative changes in v4 will come into force on 1st April 2023, effectively compelling all users to make the switch.

Therefore, we're updating Alloy to support the current v4.15 specification ahead of this deadline.

Who will be affected

This change will affect anyone using Alloy Web or Alloy Mobile to interact with the Street Manager service.

Details

Fortunately, there are only a few changes to learn about!

New permit conditions

  • NCT09d - Changes to traffic management arrangements APPLIES TO ALL MAJOR PERMITS on Category 0, 1, and 2 streets only.
  • NCT03 – Activities ancillary to those permitted – supplementary information.

For more detail, see the Statutory guidance for highway authorities.

New Traffic Management type

A new TM Carriageway Restriction Type will be available: Temporary obstruction 15 minute delay.

Footpath Closure

A new Foothpath Closure attribute will be mandatory for all permit requests.

Emergency Contact Name and Number

New Emergency Contact Name and Emergency Contact Number attributes will be optional for most permit requests, unless the chosen Traffic Management type is Multi Way Signals or Two Way Signals.

Expected Release

30th March 2023 as part of the Alloy v2.45 release.

What did you do in 2022? πŸ“…

As we reach the end of the year, it's time to look back at what we've all accomplished together in 2022. Liz and Kwarti, you can sit this one out... 😬

You loved it last year, so here it is again! We've put together a fancy webpage that you can log into to see all kinds of stats about your year in Alloy, delicately interwoven with the eccentric humour you've come to expect from us 😅

So go on, visit review2022.alloyapp.io and marvel at how busy your organisation has been this year. Feel free to share the URL of your personalised report with someone you want to impress, such as your boss or a prospective dating partner. Here's what Matthew McConaughey had to say about ours:

On behalf of the Alloy team, thanks for being with us in 2022, and we look forward to making 2023 even better 🎉

Removal of Access Policies

Overview

Alloy’s robust Permissions system gives you fine control over who has read/write access to most of the objects in your Alloy database (e.g. designs, layers, workflows).

To take this a step further, we introduced Access Policies. These are simple rules defined per design/interface, which ensure that users can only access items that can be traced back to them. For example, making job items only accessible to users who are members of the job’s allocated team.

While Access Policies work well in principle, the current implementation unfortunately comes with too much of a performance cost.

Therefore, Access Policies will be removed in the next Alloy release, to be replaced with a better implementation at a later date.

Who will be affected?

No active customers are currently using this feature, so we expect its removal to have zero impact.

Details

The /api/access-policy/ endpoints will be removed from the API. Any remaining access policies will be deleted.

Expected Release Date

23rd February 2023 as part of the Alloy v2.44 release.

Removal of old API key mechanism πŸ”‘

Overview

Back in December 2021, we announced that the mechanism for API keys would be changing.

In summary, API keys would no longer be generated automatically for every user, so new API keys must be generated on demand. Additionally, these new API keys must be passed using the OAuth 2.0 Bearer token format. For full details, please see the previous New API Key Management announcement.

These changes were implemented on 13th January 2022, with the old API keys remaining valid for a year.

Therefore, this is to remind everyone that the old API key mechanism will be removed in January 2023!

Who will be affected?

Any user or integration that still uses an old API key to communicate with the Alloy APIs.

Details

As of the release date below, old API keys that were created before 13th January 2022 will no longer be valid.

Additionally, the /api/user/me endpoint (Swagger/ReDoc) will no longer include the old apiKey property in its responses.

To learn about the new endpoints for managing API keys, please see the previous New API Key Management announcement.

How can I check my API key?

The simplest way to check if your API key is "old" or "new" is to consult your code. Does it pass the API key in the OAuth 2.0 Bearer token format (RFC 6750)? If so, your API key is new!

Alternatively, you can use the GET /api/user/me endpoint (Swagger/ReDoc) before the release date to return information about the currently logged in user. If your API key matches the value of the depreciated apiKey property in the returned user, your API key is old.

If in doubt, we recommend using the POST /api/api-key endpoint (Swagger/ReDoc) to create a new API key.

Mesh Users

If you have any workflows that use a Call Mesh action, your Alloy customer project will need updating with a new API key. We've been reaching out to customers we believe to be affected by this, but if in doubt, please contact Support to request this.

Expected Release Date

26th January 2023 as part of the Alloy v2.43 release.

New Alloy safety limits πŸ›‘

Overview

This is to inform all users that we've recently implemented three safety limits to Alloy’s engine.

These have been put in place to help ensure that the performance, reliability and security of Alloy remains high. Rest assured, these limits have been calculated carefully, so most users will never reach them!

In rare cases where a limit is reached, users will receive a detailed error message to inform them what has happened, so the situation can be avoided in future.

Who will be affected?

These limits affect all users of Alloy but will be unnoticeable by most.

Details

The following limits have been added.

Maximum Background Tasks

The number of background tasks that can be queued per customer project. This has been limited to 100,000 tasks, which is far higher than has ever been reached before.

If the limit is reached, attempting to create a task will fail with this error:

Error Category: ResourceLimited,  Error Code: 1657552956

Maximum Item Size

The size of any item being operated on. This has been limited to 2MB (roughly 420,000 words of text) for optimal resource management.

If the limit is reached, the operation will fail with this error:

Error Category: ItemSizeExceedLimit, Error Code: 1657279454

Maximum Items to Query in Bulk

The total number of items involved with any write operations. While a query may only affect a moderate number of items directly, each item may have child/parent items that need querying too. Therefore, this has been limited to 200,000 items on the Task Executor (75,000 items on the API services).

If the limit is reached, the query will fail with this error:

Error Category: BulkQueryLimitExceeded

Pickers Now Support Search Settings πŸŽ‰

Overview

When using the top-right Search panel to find items of a particular design or interface, you can customise how item attributes are searched, the collection(s) to be searched, and how the results are ordered.

However, these search settings currently apply to all designs/interfaces. This isn’t ideal, as what may be optimal for some designs/interfaces may not be optimal for others!

Therefore, as part of our continual efforts to add flexibility and improve consistency within Alloy, we’re making two important changes in this area:

  • Search settings will be saved per design/interface.

  • Search settings will affect item pickers as well as the Search panel.

Who will be affected?

These are broad changes that will affect most Alloy users.

Details

As before, when using the Search panel, you can customise your search settings like so:

  • Select the search box, enter the name of a design/interface and press Enter.

  • In the bottom action bar, select the More icon and choose Search settings.

However, when saving these settings, they will no longer be applied to all designs/interfaces. Instead, they will only be applied to the design/interface that you’re searching in.

This means you can save different search settings for different designs/interfaces, leading to a more efficient searching experience overall.

Item pickers

Search settings will be shared between the Search panel and item pickers, so saving custom settings for a design/interface in one will affect the other.

For example, imagine you’re creating a defect. In Step 2 of the procedure, you’re prompted to select the asset(s) you want to create a defect against. An item picker appears showing items of the Defects Assignable interface.

The items listed by the picker are subject to the same search settings as the Search panel. To access those settings, you can select the new cog icon (outlined in red above).

The orange dot over the icon indicates that custom settings have already been set for the design/interface being searched, which will affect the appearance and order of items shown in the picker.

Expected Release Date

8th December 2022 as part of the Alloy v2.42 release.

Changes to the ApplicableTypes endpoints

Overview

We recently added several Applicable Type endpoints to the Web API: https://announcements.alloyapp.io/applicable-types-now-enforced-by-web-api-3jpgbe

Applicable Types define how items of various activity-related designs can link to each other, e.g.

  • Which Asset types can each Job/Inspection/Defect type be linked to?
  • Which Job types can each Job Work Unit type be linked to?

When using the api/applicable-type/applicable-from endpoint, you may receive some unexpected results. Put simply, this is because the current logic is finding links that can be applicable but haven’t explicitly been made applicable.

To improve this, we’re changing how the endpoint behaves. Rather than accepting a list of designs, it will instead accept a list of items. The new logic will be able to use the parent or child items to determine which DoDIs or items are applicable from that item.

This should produce results that are more in line with expectations! However, it will require some breaking changes. 😐

Who will be affected?

These breaking changes will affect anyone who uses the ApplicableTypes endpoints on the Web API.

Details

New Endpoint Addresses

The addresses of the following endpoints will be changing.

List Applicable From Types endpoint

The request for this endpoint (ApplicableTypeFromWebRequestModel) will be changing:

  • The toAll property will be removed.
  • The from property will no longer accept a ApplicableFromItemWebModel (item IDs) and therefore will no longer require a discriminator. It will only accept ApplicableFromDodiWebModel (DoDi codes).
  • The toAllItems required property will be added (to replace toAll). This is an array of item IDs that you wish to check.
  • The filterAttributeCode required property will be added. This specifies the link attribute to find applicable types on. The attribute must be present on all the items provided in toAllItems.

For example, to query which job types can be raised against specific assets, you would provide these values for the aforementioned parameters:

  • ToAllItems = an array of asset item IDs
  • FilterAttributeCode = attributes_tasksAssignableTasks
  • From = designInterfaces_jobs
    (to exclude inspections and other task types)

Additionally, the response model for this endpoint (ApplicableTypeFromWebResponseModel) will also be changing:

  • The NoRestrictions property will be added.  If no results are returned, this boolean explains why. If true, there are no restrictions, which means everything applies. If false, it means that nothing applies.
  • The results can be of type ApplicableFromDodiWebResponseModel or ApplicableFromItemResultWebModel, so these are the new discriminators to use (no more ApplicableItemWebModel).

Importantly, this revised endpoint won’t support finding applicable job types for supplied work unit items. This will be handled by a new endpoint coming in future.

List Applicable To Types endpoint

The response for this endpoint will be changing:

  • The results can only be of type ApplicableToDodiWebResponseModel. Therefore, it will no longer be necessary to supply a discriminator.

Expected Release

8th December 2022 as part of the Alloy v2.42 release.

The documentation available on Swagger and ReDoc will be updated accordingly.

New Coordinate System picker for Imported Geometry 🌐

Overview

This is a follow-up to a recent post about an issue affecting the import of geometry data in Alloy Web.

The issue was caused by a third-party service (espg.io), which provided Alloy with a list of Coordinate Reference Systems (CRS) and the corresponding proj4 strings required for converting the incoming geometry data accordingly. Upon discovering the issue, we quickly issued a temporary workaround.

To avoid this situation repeating in future, we’ve now removed this dependence from Alloy in favour of a curated local list.

Who will be affected?

This change affects all users who use Gateway to import geometry data in Alloy Web.

Details

When configuring an import in Alloy, there are two optional steps in the procedure that involve imported geometry:

  • Attributes – in this step, you can map headers in the incoming data to attributes on the selected design. After selecting a GeoJSON attribute, you can select the Coordinate System field and choose one from the list (see below).

  • Geometry – in this step, you can specify the type of geometry data to be imported. After selecting a Type, you can select the 🔍 icon in the Coordinate System field and choose one from the list (see below). Unlike the previous step, the full proj4 string will appear in the field, so it can be edited if necessary before selecting Done.

The coordinate system will default to WGS84 Lat/Lng if not explicitly set.

If you have any existing imports that include geometry data and have a Status of Configured or Validated, we recommend reconfiguring them. To do this, open the import item, select More in the bottom action bar and choose Reconfigure.

Available Coordinate Systems

We’ve included the most popular coordinate systems to choose from. Any others we should add? Please feel free to contact Support with your suggestions!💡
