This seems like it should be so simple, but I am just not getting it!
My
@photo = Photo.find_by_project_id(params[:photo => :project_id])
(also have tried (params[:photo]
[:project_id]
in PhotosController statement always evalutates to nil,
if @photo != nil
@photo.update_attributes(params[:photo])
even though the project_id is in the params hash:
(output from my application log:)
Parameters: {"photo"=>{"project_id"=>"371", "user_id"=>"14",
"lwrimg"=>#<File:/tmp/RackMultipart.26504.0>}, "page_path"=>"projects/
edit", "authenticity_token"=>"iiwoOHgAaBTCv/U4xhmvlR2qleLbG
+Ov70cubJ7G8jQ=", "after_submit"=>"stay-here"}
...so the project_id is set.
However, the SQL query is:
[4;35;1mPhoto Load (0.2ms)[0m [0mSELECT * FROM `photos` WHERE
(`photos`.`project_id` IS NULL) LIMIT 1[0m
...which seems to indicate that (params[:photo => :project_id]) is
returning NULL,
or that I am misunderstanding
@photo = Photo.find_by_project_id(params[:photo => :project_id])
I thought the above would be that @photo is a copy of the record found
in the d.b., and
thus I would be able to use the test:
if @photo != nil
So, what is the correct way to update a record if it exists?
Cheers,
Jet
