In place select editor field posted by russell Roberts @ Sun, 13 Apr 2008 11:57:47 -0000

I am using this succesfully if I follow the example and use the country collection for the select.

Should it be possible to edit a has_many field?

I have product belongs to category and category has many products

So in my show view of the product I have

<%= product.category.name if product.category_id %>

and in my new I have

<%= f.collection_select :category_id, Category.for_collection,:id,:name %>

So I am not sure how to get this to work with In place select editor field.

Thank you Russell

Xhtml functionality in Html file posted by Bob Barry @ Fri, 25 Jan 2008 21:04:58 -0000

Bob Barry — Fri, 25 Jan 2008 21:04:58 -0000

Firefox and Internet Explorer appear to look at the incoming file tag to decide whether to treat the file contents as Html or Xhtml. Using Rails, I’d like to make templates that include Xhtml elements having MathML and SVG. Innocently, I thought I could get the browser to think Xhtml by finding the right DOCTYPE and META lines within a file having tag html.
I still think that must be right, but I haven’t figured out how to write the DOCTYPE and /or META lines.
All ideas will be welcome.

To be clear: A file opened by Firefox containing an <svg> element will render the circle on the browser page PROVIDED the file’s tag is Xhtml or Xml. Say, ‘circle demo.xhtml’ but if the file tag is changed ‘circle demo.html’ then Firefox will not render the circle.
Thanks.

In the “raise() is your friend” box on page 6, you talk about adding the method set_contact_name. It would be useful if you mentioned where that should be added. Does it go in contact_controller.rb? I tried this and it didn’t seem to work. Putting it in the model doesn’t make sense. Maybe it goes in the rhtml file somehow…

Adam

“Regarding authorization based on roles/rights as assigned to controller & action (Recipe #32). I am realizing that I have to add an entry for every single method I come up with in my controllers. Is this the intended functionality, or am I twisted around backwards on this? It seems like a heck of a lot of extra inputing/configuring. I just added 6 methods and realized that I can’t access any of them until I add a row for each one (per accessible role) in rights_roles table.

Is there a way to give a single role access to all methods in a controller? Or pehaps by using some sort of naming convention, have it so that any method that starts with ADM is automatically accessible by administrators and any that start with USR is accessible to users?”

@RWalker

I agree. I’m facing this same situation. I have about 10 controllers in my app with at least 4 actions each and that adds up to a lot of rows in the rights table.

That’s not soo bad, if you just automate the insertion in the dev enviroment (I made a simple rake task). However, I’m even more confused on how to test it. Actually how to add roles to my user in my test fixture. Since User.roles only exists in rails and not in the db, how am I supposed to represent this?

administrators: id: 1 name: Administrators rights: How do I add a right to the rights array with fixtures?

From what I can gather to date, the acts_as_taggable plugin (the DHH plugin specifically) has been retired and is no longer being maintained. The latest version of the README states that it was intended as a proof-of-concept module, and was not ever intended to be used for production code. A thread in the rubyonrails-core news group supports this. See http://www.ruby-forum.com/topic/124063#552714 for links to both sources.

In all the rails tutorials I’ve seen they boast about how important and easy it is to hash password in the DB. However, I see none of them address the issue of the password being transmitted in plain text once once the user licks “Login” on the client. Is everybody assuming that SSL is in use?

i recently experienced the same problem, but turns out the problem was stupid programmer syndrome…

this error also shows up if you name your migration file something like “097_CreateAccounts.rb” instead of “097_create_accounts.rb”

go figure. at least fixing this was a heck of a lot easier than reinstalling rails.

Great post, Maxim.

To take it even further, you can use any partial to act as a layout:

application_helper.rb


def inside(partial, AMPERSANDblock)
  instance_variable_set(:@content_for_layout, capture(AMPERSANDblock))
  concat(render(:partial => partial), block.binding)
end

_wrapper.rhtml (the outer layout partial)


<div id="wrapper">
  <%= yield %>
<div>

content.rhtml (the actual template)


<% inside "wrapper" do -%>
  Inside the wrapper
<% end -%>

Result:


<div id="wrapper">
  Inside the wrapper
</div>

This is completely compatible with the standard Rails layouts. They’ll work like they did before.

However, I don’t know if this plays well with page caching. Testing this is left as an exercise for the reader :)

I recently purchased Rails Recipes. It has been a great adition to my many other PP books. However:

Recipe 31: Authenticating your users.

This is a ‘half baked’ recipe. Considering many Rails newbies could be following along, why are we not shown how to display a friendly message if the user or pass are incorrect?

This is extremely frustrating. I have tried all the suggestions on this forum and still have no clue. I have wasted nearly a day trying to solve this.

Why would I want to display Runtime error instead…..

Asa, you saved my evening. I’ve been pulling my hair out trying to figure out why the message_id was there when I was testing locally, but failed on the production server. The difference was smtp vs. sendmail, and your fix corrected it.

This app was frozen to Rails 1.2.1, but checking the source for 1.2.3 and edge it does not appear that this has been corrected. Is this a bug in Rails, or is there something other than Asa’s fix that apps should be doing?

Hi, I cant get this example to work properly with google or yahoo mail clients, I copied code and followed directions, but when I get email in gmail or yahoo its an empty email, when I view details I can see the multipart message but neither of these popular mail clients understand this message.

It does look nice for mac mail client :)

Also when I try in my app using active record objects passing in I get nil object issues also.

Using Rails 1.2.3 and ruby 1.8.4

I was able to use Jeffrey Hicks’ Many-to-Many tutorial to flesh out the roles and rights user interface options.

I’m still having a problem with logging in. I can login fine, but then I get: Routing error Need controller and action!

I need a way to send everyone to a default page… since a new login didn’t redirect from a particular controller/action

I’m having a great deal of difficulty getting this to work. I can login with a base account. Once I added roles, it worked in a basic way but the explanations and tools leave a lot to be desired. Things like add-user, assign-roles/rights, etc, would be helpful.

Based on the comments in the forum it seems like recipes 31 & 32 are not useful in their present state.

Will there be any updates/errata to download for those recipes?

Re: Authentication

For those who asked about getting the error raised in the User model in the controller, the following worked for me in my Admin controller:

def signin 
  if request.post? 
    begin
      session[:user] = User.authenticate(params[:username], params[:password]).id 
      redirect_to "" #you can put your action/controller here
    rescue
      flash[:notice] = "Username or password invalid" 
    end
  end 
end

Now my question is: Is this a good coding practice? I’m not sure, but it seems the flash is based on a rescue for all raised errors. Perhaps there is a better way to have a skinny controller and flag the error in the model?

After much wailing and blood on the forehead I got around the validation issue by adding:

attr_accessor :password, :password_confirmation

to the top of the class then updating the password method to include @password:

def password=(pwd)
  @password=pwd
  self.password_salt = [Array.new(6){rand(256).chr}.join].pack("m").chomp
  self.password_hash = encrypt(pwd plus self.password_salt)
end

Can now validate till me heart’s content ! Can someone tell me why?

I struggled with an issue like this one that I spent quite some time on. What you need to do is to do something like this:

def password=( string )
    write_attribute( :password, encrypt( string ) )
end

Also make another method in the model that looks like this:

def password_confirmation=( string )
    @password_confirmation = encrypt( string )
end

Rails will use these methods to compare the two password strings in a validates_confirmation_of but also counts on the instance variable being there for the password_confirmation.

Remember: write_attribute for the actual password AND set the instance variable for the confirmation.

I have the same problem as some of the other posters – I cannot make the recipe work for the registration process: my user records are created without any password or salt entries.

I wonder why the author left this (one would have thought essential) element out of the recipe?

More disturbing, I see posters with this problem dating back to October – It is now May and I don’t see any posts with a fix.

Does anyone who knows anything about RAILS ever looik at this site, or are we just typing into space?
