[Rails] Re: Rails is slow to load

2010-08-04 Thread Eric Yen 
That did cross my mind, but I was just wondering though.
Mostly because it didn't look as though the transition from running
the command to the actual test running wasn't edited.

But oh well.

[Rails] Rails is slow to load

2010-08-04 Thread Eric Yen 
Hi,

I was just wondering if this was normal or not.

I was running ruby 1.8.7 with rails 3 - rc. (Currently trying 1.9.2-
rc2 but the same problem)
It takes rails a while to load. (a while as in 10-15 seconds)
It will take a while before I can use the console , or before running
a test or starting up the server.

This doesn't seem normal to me when I watch some screencasts.
If this is not normal behaviour, how can I figure out the source of
the problem?

Thanks.

I was under the impression that change_column was only for renaming.

[Rails] Migration: updating a column

2010-07-29 Thread Eric Yen 
Hi,

Is there a way to "update" a column?

Here's what I mean:
I have a column name "item" in table "products" of type "integer"
Now I want to update the  column to have the option ":null => false"

So far, the only way I have found is to remove it and re-add it, but
obviously that is quite dumb.

[Rails] Test - Skip Setup

2010-07-27 Thread Eric Yen 
Hi,

I want to write a functional test using the default test unit  that is
included with rails 3.
Is there a way to skip a setup call?

So I'm trying to test the users controller.
But to access those actions, I need to be logged in. So I put a login
algorithm in my setup.
But I do not need to be logged in to create a new user. This is why I
want to skip the setup call.

[Rails] Rails 3 - AJAX Response

2010-06-22 Thread Eric Yen 
Hi,

I need help with some AJAX in rails 3.

So basically, I have a select option in my index page for my User
model. This select option is a form that modifies the user's type. The
" :remote => true " works and the type is changed when hit the submit
button. But, nothing happens in the browser. The user is updated.

I'm actually not sure where to put either my JS / RJS file ( I've
tried both, but neither do anything.  )

So here's my code:

The form:

   <%= form_for(@user, :remote => true) do |f|  %>
<%= f.select("type_id" , Type.all.collect{ |t|
[t.name,t.id] } ) %> #TYPE is another model. User belongs_to Type
<%= f.submit "Save"  %>
<% end  %>



The model:

class UsersController < ApplicationController
  skip_before_filter :authorize, :only => [:new, :create]
  # GET /users
  # GET /users.xml
  def index
@users = User.all

respond_to do |format|
  format.html # index.html.erb
  format.xml  { render :xml => @users }
end
  end

  # GET /users/1
  # GET /users/1.xml
  def show
@user = User.find(params[:id])

respond_to do |format|
  format.html # show.html.erb
  format.xml  { render :xml => @user }
end
  end

  # GET /users/new
  # GET /users/new.xml
  def new
@user = User.new

respond_to do |format|
  format.html # new.html.erb
  format.xml  { render :xml => @user }
end
  end

  # GET /users/1/edit
  def edit
@user = User.find(params[:id])
if params[:change_type]
change_type
end
  end

  # POST /users
  # POST /users.xml
  def create
@user = User.new(params[:user])

respond_to do |format|
  if @user.save
format.html { redirect_to(@user, :notice => 'User was
successfully created.') }
format.xml  { render :xml => @user, :status
=> :created, :location => @user }
  else
format.html { render :action => "new" }
format.xml  { render :xml => @user.errors, :status
=> :unprocessable_entity }
  end
end
  end

  # PUT /users/1
  # PUT /users/1.xml
  def update

@user = User.find(params[:id])

unless params[:user][:type_id]

@user = User.find(params[:id])

respond_to do |format|
  if @user.update_attributes(params[:user])
format.html { redirect_to(@user, :notice => 'User was
successfully updated.') }
format.js
format.xml  { head :ok }
  else
format.html { render :action => "edit" }
format.js
format.xml  { render :xml => @user.errors, :status
=> :unprocessable_entity }
  end
end
else
  respond_to do |format|
if @user.update_attribute("type",
Type.find_by_id( params[:user][:type_id] ) )
  format.js{ head:ok}
else
  format.js {head:ok}
end
  end

end

  end


  def change_type
unless params[:change_type_value]
  if   @user.category == 5
  @user.category = 0
  else
@user.category = 5
  end


  respond_to do |format|
if @user.save
  format.html { redirect_to( users_path, :notice =>
"Sucessfully changed " + @user.name.titleize + "'s category" ) }
  format.js
else
  format.html { redirect_to( users_path, :notice => "Failed to
change " + @user.name.titleize + "'s category" ) }
end
  end
end
  end

  # DELETE /users/1
  # DELETE /users/1.xml
  def destroy
@user = User.find(params[:id])
@user.destroy

respond_to do |format|
  format.html { redirect_to(users_url) }
  format.xml  { head :ok }
end
  end


end



The Response:

[Rails] SQLite - show html from entry

2010-06-18 Thread Eric Yen 
Hi,

I have an entry in my database that has line breaks.
I want those line breaks to actually appear as line breaks when the
entry is displayed.

So, I did something like:

<%= string_var.sub("\n","":) %>

It partially works. It actually replaces the < with < and the >
symbol with >.
Is there a work around this?

Thank you,
Eric
