Mixin rendering a component

[Imants Firsts <im...@inbox.lv>]

Can mixin render a component, for example TextField? I
know that that it does not support templates and that
it can render the <input> tag directly.
But I would like the mixin to add a component to form,
so that it can be processed when the form is submitted.
Is something like that possible with mixins?

Actually, that's an interesting point. In general, I don't do crawlable
apps, so it's not an issue.

Keep the list out of your main form.  In the list, generate a column that
contains a form (one for each row) with the context set to the id of the
item to be deleted. Submit button now triggers your delete.

Same approach - different tool.

I consider ActionLinks wrong from the architectural
perspective. You really should not send GET requests
which deletes entities. Any crawler that crawls such a
page would be devastating.

RE: Mixin rendering a component

[Jonathan Barker <jo...@gmail.com>]

Would it be acceptable to keep the list outside of the form, and use
ActionLinks with the id's of the items to be deleted?

You could then have a conditional on your list component for whether or not
the column with the ActionLink is displayed.

Re: Mixin rendering a component

[Imants Firsts <im...@inbox.lv>]

I have an entity with one-to-many relationship to other
entity - i.e. this entity contains a field of type
List<Entity2>.

I have a component which displays this list of objects.
For normal screen I just use this component. But for
edit screen for the main entity I would like to add
some functionality to my list component - i.e. add a
Delete button for each item, which would submit the
enclosing form.

I wanted to use Mixin, since I can't extend template
and override some part of it like I can do with java class.

I think the solution could be to for my edit component
to extend the view component and completely override
it's template, by duplicating it and adding the Delete
buttons.

I don't see any way to render a component from a mixin. I'm not sure
of a use case where you'd want to do that with a mixin. Can you tell
us what you are trying to do? Then maybe someone can offer another
solution.
