v0.14.0 (Beta 27.08.2021)

[mpscholten]

A new IHP release with new features and many bug fixes. This release is also the first release that comes with an IHP Pro release 🚀

Major Changes

• Allow scheduling jobs at a specific time with runAt:
  The job queue table's now have a run_at column. Jobs are only executed after the specified time.
  The job runner is now also polling the job queue at regular intervals as otherwise scheduled jobs will not be picked up when there's no activity on the job queue table.

  Here's an example of a job scheduled to run in ten minutes from now:

  inTenMinutes <- addUTCTime (10 * 60) <$> getCurrentTime
  newRecord @DeleteContainerJob
      |> set #containerId (get #containerId containerBuild)
      |> set #runAt inTenMinutes
      |> createRecord

• New IHP Logo:
  The dev server now displays our new beautiful IHP logo 💘
  

• Customize File Upload Limits:
  By default IHP has a max file size limit when uploading files to the IHP server. You can now customize these limits inside your Config/Config.hs.

  Learn more about this in the docs.

• 📫 Email Confirmation:
  One of the first IHP Pro features now made it :) There's now a built-in standard way to deal with email confirmation.

  Check out the documentation on how to set this up

• OAuth:
  Login with Google and Google are now finally available in IHP.

  This new feature is also part of IHP Pro. Once you're app is running IHP Pro, follow this Guide on how to set it up.

• New Form Helper: fileField:
  Previously you had to manually type the HTML code for <input type="file"/> fields in your forms. We've finally added the missing helper 🎉

  renderForm :: Company -> Html
  renderForm company = formFor company [hsx|
      {(textField #name)}
  
      {(fileField #logoUrl)}
      
      {submitButton}
  |]

• New Function: createTemporaryDownloadUrlFromPathWithExpiredAt: Get signed S3 download urls with a custom expiration time
  This function is similiar to createTemporaryDownloadUrlFromPath, but you can pass a custom expiration time. The createTemporaryDownloadUrlFromPath function always generates urls that are valid for 7 days.

  E.g. this example generates a presigned S3 url to a logo that expires in 5 minutes:

  let validInSeconds = 5 * 60
  signedUrl <- createTemporaryDownloadUrlFromPathWithExpiredAt validInSeconds "logos/8ed22caa-11ea-4c45-a05e-91a51e72558d"
  
  let url :: Text = get #url signedUrl
  let expiredAt :: UTCTime = get #expiredAt signedUrl

• Improved Support for GitPod & GitHub Codespaces:
  Previously IHP's dev tooling was only running when it was called at localhost:8000. This is a problem in services like GitPod or GitHub spaces, where the the host might not be localhost.

  There are now two env variables IHP_BASEURL and IHP_IDE_BASEURL to override the BaseUrl configured in Config/Config.hs at runtime:

  export IHP_BASEURL=http://dev.myhost.lo:1337
  export IHP_IDE_BASEURL=http://dev.myhost.lo:1338
  ./start
  

  We've already integrated this into the IHP GitPod template. If you're curious, follow this link to start a GitPod development session (it's free) with the IHP Template.

  These new env vars might also be useful if you run your IHP dev tooling on a different device than your editor inside your local network.

  

Other Changes

• Fully evaluate blaze html expression before returning the html response in dev mode. This improves error messages when there's an error call inside a view.
• Fixed many-to-many relations with Int PKs
• refuse to build union query if one of the queries contains joins
• Fixed deleteRecord for composite PKs. Fixed several bugs in code generation for composite PKs
• Fixed issues with loading IHP tests into ghci
• Pagination functions now also work with queries that have a JOIN
• Simplified constraints required for calling isNew: We can detect if a record is new by checking the originalDatabaseRecord field of the meta field. This allows us to drop the constraints that require the form record to have a id field. This allows to use formFor with records that don't have an id field.
• Keep message through multiple redirects
• Fixed crash in SchemaCompiler if the enum has no values.
• Added Int type to SQL Parser: Previously all Int's have been handled like variables (in a way that makes sense :D 1 is just a symbol standing for number 1). This has caused issues as we introduced support for Double literal expressions recently. Now integer literals have their own representation in the AST.
