How to use the custom filter?

Support
#1

Hello :slight_smile:

I would like to use a custom filter. I have an entity - let’s call it T and it has a many-to-many link to entity named Tags.

So I can start the application and define a new search condition in filter, using the following criteria:

  • condition name: tags
  • join: e.tags t
  • where: t.name like ?
  • parameter type: String

And it is working as expected.

Now, I would like to get the same effect using CUBA Studio 6.10. So I go to browse screen, go to filter component, click on “Custom” and I have to enter the following data:

  • name: tags
  • caption: Tags
  • paramClass: java.lang.String
  • inExpr - unchecked
  • query - what should I enter here?
  • join - e.tags t - is it right?
  • paramWhere - t.name like ?
  • paramView - empty

But then nothing happens, I can select “Tags” from the condition list but this does not seem to modify my query.

What am I doing wrong?

Hi,

Custom filter conditions are explained here in the docs.

After defining one, the condition is available for selection in the Add condition dialog:

When the user adds the condition to the filter, it works as any other conditions.
