Rails: Partial Form Conditional Path
I have two forms for new and editing, which I want to extract into partial, but for my initial knowledge of Rails they need different paths to work.
This is my edit form:
<%= simple_form_for [@user, @wiki], url: user_wiki_path do |f| %>
<%= f.input :title %>
<%= f.input :body %>
<%= f.submit class: "btn btn-success" %>
<% end %>
This is my new form:
<%= simple_form_for [@user, @wiki], url: user_wikis_path, method: :post do |f| %>
<%= f.input :title %>
<%= f.input :body %>
<%= f.submit class: "btn btn-success" %>
<% end %>
Can I, and if so how, can I combine them into one partial _form.html.erb conditionally defining paths?
When I try to join them, I get the following error when I try to edit it:
No route matches [PATCH] "/users/32/wikis"
These are my routes:

You can publish local variables in a partial. The following will work:
new.html.erb
<%= render partial: '_form', locals: {url: user_wikis_path, method: :post} %>
edit.html.erb
<%= render partial: '_form', locals: {url: user_wiki_path(@user, @wiki), method: :post} %>
_form.html.erb
<%= simple_form_for [@user, @wiki], url: url, method: method do |f| %>
<%= f.input :title %>
<%= f.input :body %>
<%= f.submit class: "btn btn-success" %>
<% end %>
Or you can set @url and @method as instance variables and access them that way.
controller
def new
@method = :get
@url = user_wikis_path
...
end
def edit
@method = :post
@url = user_wiki_path(@user, @wiki)
...
end
_form.html.erb
<%= simple_form_for [@user, @wiki], url: url, method: method do |f| %>
...
Or you can have a conditional expression on the form that refers to the current action, if you use the name action_ in the view it will return the name of the current action.
