My overall use case:
I have a Listing model that has many images. The Listing detail page lists all the fields that can be updated inline (through ajax).
I want to be able to use the same
view for both update listing and create new listing.
My listing controller looks as follows:
def detail
@listing = Listing.find(params[:id])
@image = Image.new #should this link somewhere else?
respond_to do |format|
format.html # show.html.erb
format.xml { render :xml => @listing }
end
end
def create
# create a new listing and save it immediately. Assign it to guest, with a status of "draft"
@listing = Listing.new(:price_id => 1) # Default price id
# save it to db
# TODO add validation that it has to have a price ID, on record creation. So the
view doesn't break.
@listing.save
@image = Image.new
# redirect_to "/listings/detail/@listing.id" #this didn't work
respond_to do |format|
format.html # show.html.erb
format.xml { render :xml => @listing }
end
end
The PROBLEM
I'm using a partial that shows the same form for the create
view and the detail
view.
This works perfectly except for one thing:
When I pull up
http://0.0.0.0:3000/listings/detail/7, it works perfectly.
When I pull up
http://0.0.0.0:3000/listings/new, I get the following error:
Showing /Applications/MAMP/htdocs/rails_testing/feedbackd/app/views/listings/_edit_form.html.erb where line #100 raised:
No route matches {:action="show", :controller="images"}
Extracted source (around line #100):
97: <!-- Form for new images -->
98: <div class="span-20 append-bottom">
99: <!-- <%# form_for :image, @image, :url => image_path, :html => { :multipart => true } do |f| %> -->
100: <%= form_for @image, :url => image_path, :html => { :multipart => true } do |f| %>
101: <%= f.text_field :description %><br />
102: <%= f.file_field :photo %>
103: <%= submit_tag "Upload" %>
What I think the issue is:
When I upload a new image (I'm using Paperclip), it requires the listing_id to create the image record. Since the listing_id isn't passed in with listings/new it can't find the listing_id. How can I pass in the id? Via a redirect? What's the best way to solve this? Thank you.
