I have a form that I’m trying to render the same way for the new action as it is for the update action via
<%= render “form.html”, changeset: @changeset, action: post_path(@conn, :update, @post) %>
I’m using this in both new.html.exs and update.html.exs (“note the :update in the post_path”)
The issue I’m having is that some how the form_for is inferring which method the form should use by rendering a hidden input of <input name="_method" type="hidden" value="put"> for only the update.html.exs but not the new.html.exs
When looking at the form_for itself there is nothing indicating how it knows when to generate the hiden form input or not.
<%= form_for @changeset, @action, fn f -> %>
The action in this case is just the path of the post_path, but nothing is specifying which method should be used.
I understand that I can supply a method option to the form_for, but my question is how does it infer it if nothing is given?
