ruby on rails 3 - Why is user.save true but email shows as nil? -

-

I am using a nested model form for sign-up and working through kinks as a start I am A problem that came up specially, although I do not actually find it returning as user.email back to zero .

Before I started playing with the nested model form, I can make a record in the console for a problem. Now, though I can not create records and the latest records are made in their email as zero (I'm not sure there is nothing with the model in it, but this is my reference point When he starts messing up.)

If I go to Rail Console to create a new user / profile, I follow this process: 

  user = user. New user.mail = "" user.password = "" user.profile = profile.new user.profile.first_name = "" ... user.profile.save user.save   
 Everything goes fine up to user.save, which gives me an error named : Undefined local variable or # & lt; User: & gt; For the method 'parameter'  in the Rail Console,  it pins user.rb:  create_profile    
 in 25 User model is:  
  class user & lt; ActiveRecord :: Base attr_accessor: Password: Email has_one: Profile ,: Dependent = & gt; : Destroys accepts_nested_attributes_for: Profile Valid: email, uniqueness = & gt; True,: length = & gt; {: Inner = & gt; 5..50},: format = & gt; {: With = & gt; / ^ [^ @ <[\ W]] + @ [[w -] + [[]] [a-z] {2,4} $ / i} is valid: password, confirmation = & gt; True,: length = & gt; {: Inside 4..20} ,: = Appearance => True if, if & gt; :Password required? Before_save: encrypt_new_password after_save: create_profile def self.authenticate (email, password) user = find_by_email (email) comes back to the user if user & amp; Amp; User.authenticated? (Password) end deaf certified? (Password) self.hashed_password == encrypt (password end protected encry encrypted_nu_password return if password.blank? Self.hashed_password = encrypt (password) enddef password_required? Hashed_password.blank? ||   
 Does anyone help me to understand what is happening?  
  
 Update strong:  I tried to change my regex, but I still I am seeing zero for the email, although a former SO post regex without any test So I probably did not test it properly, though: I no longer found any errors.   
 
 
  attr_accessor  just a" property "and an activated code ( attributes  a  hash )  attributes ) have no relation to the table).  
 ActiveRecord is defined by such "properties" as  attr_accessor . (Basically,  attr_accessor  a  attr_reader  and attr_  author  (i.e. "getter" and "setter") at the same time define)

mysql - BLOB/TEXT column 'value' used in key specification without a key length -

-
I have developed an extension which works up to 1.6 on Magren (I'm trying Enterprise Edition, And I think the community is the same problem, because it is the same code). In my install script, I see the $ installer-> gt; CreateEntityTables ($ this- & gt; getTable ('alphanum / info')); The installation is done until it is not in the _text unit table. It crashed there! It turns out that when I log in to SQL and run it via PHPmyadmin, then this error is: Blob / Text column 'value' is used without the key 'key' . I saw the code there, and this is what is trying to create an index on the value column: -> addIndex ($ this- & gt; getIdxName ($ eavTableName, array ( 'attribute_id array (' attribute_id ',' value ')) - & gt; addIndex ($ this- & gt; getIdxName ($ eavTableName, array (' entity_type_id ' , 'Value')), array ('entity_type_id', 'value')) If there is no if statement is n...

memcached - Django cache performance -

-
We are now using Redis for in-memory cache for our Django application (we used the first memcatch The difference in performance is no big, and we're using Redis because the disc dump feature). The problem is that Django cache's performance in my view - terrible, we have a view with 102 cache hits (no miss), and it has 81 ms (only the cash part, which is with the DJBugBug toolbar Is measured). In my opinion - this is a very long time, I know, asking for a question for DB can be 10x more (or 100x) time, but that is also not good with cash performance of that fact. We are running radis (and the first memacatch) on different hosts, connected to the local network with other servers. Is there a way to maximize cache performance in Django? Instead of displaying problem cache, there is a possibility of the number of items to be received for each page 102 Cash calls mean long time lost due to network latency. With full control of the code, you may be able to fix it with m...
