&amp in url: this is driving me nuts!

Rails
1

hi i have a weird problem:

this is my view:

<%= start_form_tag :action => 'new_beschikbaarheid', :behandelaar_id =>@behandelaar, :year => @year%> behandelaar<%= collection_select("behandelaar",'id',Behandelaar.find(:all),:id,:naam) %> <%= submit_tag 'Opzoeken' %> <%= end_form_tag %>

when i hit the submit button i get this url:

http://localhost:3000/admin/new_beschikbaarheid?behandelaar_id=1&amp;year=2006

where does the amp sign come from and better: how can i get rid of it:
i sure hope someone can help me, i don’t know what to do anymore…

Regards,
Remco

i’m not sure of the details but i believe (just a hunch) the answer lies
within the notorious ‘h’ - a protector for html code…

search rails for

h

sorry for not being more informative, maybe someone else out there can
give u more specifics. . .

This is a known problem with some of the tag helpers that handle URLs
– they double-escape the URL so that & becomes &amp; instead of
just & in the HTML.

I’ve written a patch to fix this, but it’s not been accepted yet:

http://dev.rubyonrails.org/ticket/5928

In the meantime you could work around it with some ugly code like this:

Alternatively you could write yourself a custom route so that the
generated URL doesn’t contain any ampersands:

map.connect ‘:controller/new_beschikbaarheid/:behandellar_id/:year’

or something like that.

Google G. ate my code! But you get the idea – just manually write
the form tag, and call url_for to write the action attribute.

This bug should be fixed, but I’d suggest not to mix GET and POST
(default) methods anyway. You can use hidden fields for additional
parameters:

<%= start_form_tag :action => 'new_beschikbaarheid'%> <%= hidden_field_tag :behandelaar_id, @behandelaar %> <%= hidden_field_tag :year, @year %> behandelaar<%= collection_select("behandelaar",'id',Behandelaar.find(:all),:id,:naam) %> <%= submit_tag 'Opzoeken' %> <%= end_form_tag %>

You’re not mixing GET and POST; you’re just POSTing to a URL that
happens to have some querystring parameters. And, with Rails’ routes,
the difference between

/user/edit/1

and

user/edit?id=1

is pretty slender. They both end up as params[:id] = 1. So every time
you submit a form to /user/edit/1 (which is standard practice in
Rails), you’re effectively POSTing to a URL with querystring
parameters; it’s just that routing hides the ugliness of ?s, =s and &s.

My bad, I should have said “I’d suggest to avoid passing parameters in
url
with POST” :slight_smile:

i just did this

  def url_for(options = {}, *parameters_for_method_reference)
    if options.kind_of? Hash
      options = { :only_path => true

}.update(options.symbolize_keys)
escape = options.key?(:escape) ? options.delete(:escape) :
true
else
escape = true
end
url = @controller.send(:url_for, options,
*parameters_for_method_reference)
escape ? html_escape(url).gsub(/&/,"&") : url # replaces
the ‘&’ with its original &
end
