QUESTION
Bear with me, I am new to posting and Rails so sorry if I mess up phrasing!!
I am working on a Rails app with many similar models. Each view has a _form.html.haml
partial that differs in content but contains similar components, such as buttons to submit, delete, etc. Every model has_many_attached photos, and in the form you can add or delete photos. The haml for deleting photos looks like this, where variable is replaced with whatever view _form.html.haml
is in:
ANSWER
Answered 2022-Mar-03 at 19:34If I'm understanding the structure properly, it sounds like you would want to do something like the following:
Create a top-level controller that handles deleting images- This could be used by any page.
- This would require the following query parameters:
id
the photo's ID to delete by.redirect
where to redirect the user after the action is completed.
Now there will only be 1 route to handle the controller above.
Create a reusable partialFor rendering a collection of images with a redirect url that allows you to set the following state for the partial:
photos
a collection of images to render.redirect_url
this is passed as a query parameter to the centralized delete image controller.
This should be able to DRY up your implementation. Currently the only thing I see that couples the view with the deletion is the redirect URL. By abstracting that out and moving that essentially to a parameter for the partial will allow for re-use and flexibility.
You've already identified your coupling via @VARIABLE
, here's a quick mock of how I would expect it to end up looking like:

Answered 2022-Jan-01 at 11:06The application.html.erb
file is the template for the whole Rails application. Alchemy pages have their own templates per page_layout

You are able to set the layout used in the admin page edit preview with the admin_page_preview_layout
setting in the config/alchemy/config.yml

Answered 2021-Nov-30 at 00:13Just tell Capybara what you expect it to find on the page and maximum time to wait for that to appear. In your question you say that you're expecting the button to change from "Count" to "Edit" but then your code is checking for "Loose Count" so I'm not fully clear on exactly what visible change you're expecting, but assuming the latter you could just do something like
