Description
I have a custom form builder but since I want to be able to use the default one as well I created helper method for it:
# form_helper.rb
module FormHelper
def my_form_with(**args, &block)
form_with(builder: MyFormBuilder, **args, &block)
end
end
And when I try to use it inside any component I get two different results but neither of them is what I expect it to be. One renders the block twice - before and inside the form tag. The other one renders the block only before the form tag.
Note that when I use the form_with directly in the component's template it works so this has something to do with it being called from the helper.
Steps to reproduce
Create helper that receives &block, pass that block to any rails helper like form_with, link_to, etc. Use the created helper in the component.
Expected behavior
It should render the block inside the form tag and only once. The same way it works when used outside the component
Actual behavior
Example 1:
# component.html.erb
<%= helpers.my_form_with do %>
Example string
<% end>
Result:
Example string
<form action="..." method="post">
Example string
</form>
Example 2:
# component.html.erb
<%= helpers.my_form_with(model: Model) do |form| %>
<% form.text_field(:title) %>
<% end>
Result:
<input id="model_title" type="text" name="model[title]">
<form action="..." method="post">
</form>
