In my controller I have:
# PUT /clubs/1
# PUT /clubs/1.xml
def update
@club = Club.find(params[:id])
if params[:club][:logo_big] && params[:club][:logo_big].size > 0
@club.logo_big = params[:club][:logo_big].read
end
respond_to do |format|
if @club.update_attributes(params[:club])
flash[:notice] = 'Club was successfully updated.'
format.html { redirect_to(@club) }
format.xml { head :ok }
else
format.html { render :action => "edit" }
format.xml { render :xml => @club.errors, :status
=> :unprocessable_entity }
end
end
end
def image
data = Club.find(params[:id]).data
send_data data, :disposition => 'inline'
end
In my edit view I have:
<% form_for (@club, :html => { :multipart => true }) do |f| %>
<%= f.error_messages %>
<p>
<%= f.file_field :logo_big %></p>
<p class="submit_button">
<%= f.submit 'Update' %>
</p>
<% end %>
My DB has a table called clubs with a BLOB field called logo_big
When I click update I get an error along the lines of: "private method
`gsub' called for #<Tempfile:0x7213138>"
What am i doing wrong? Did I mess up the syntax of the form? I'm
working off the generated views that Rails provides.
