Rails not showing validation error messages -


Hi guys, I'm new to rail and just making my first registration form. I have some assumptions that I have to check the rail, but for some reason this error message does not show.

I have this on my / user / signup.html.erb 

  & lt; H1 & gt; Sign up now! & Lt; / H1> & Lt;% form_for: user, @U,: url = & gt; {: Action = & gt; "Signup"}. F | & Gt%; & Lt;% = f.error_messages: header_message = & gt; "Please try again!" ,: Message => "We have your registration"% & gt; & Lt;% = f.label (: first, "first name")% & gt; & Lt;% = f.text_field (: first)%> & Lt; Br / & gt; & Lt;% = f.label (: last, "last name")%> & Lt;% = f.text_field (: last)%> & Lt; Br / & gt; & Lt;% = f.label (: Username, "Username")% & gt; & Lt;% = f.text_field (: username)% & gt; & Lt; Br / & gt; & Lt;% = f.label (: password, "password")% & gt; & Lt;% = f.password_field (: password)% & gt; & Lt; Br / & gt; & Lt;% = f.label (: password_confirmation, "Confirm Password")% & gt; & Lt;% = f.password_field (: password_confirmation)%> & Lt; Br / & gt; & Lt;% = f.label (: email, "e-mail")%> & Lt;% = f.text_field (: email)%> & Lt; Br / & gt; & Lt;% = f.label (terms_of_service, "I agree to the terms of service")%> & Lt;% = f.check_box (: terms_of_service)% & gt; & Lt; Br / & gt; & Lt;% = f.submit ("Sign Up")% & gt; & Lt;% end% & gt; I have the following on the

model 

  class users & lt; ActiveRecord :: Base validates_length_of: user name, inside => 4..15 validates_length_of: password ,: inside = & gt; 3..520 validates_presence_of: first, last ,: username ,: email, password: password_confirmation validates_uniqueness_of: username,: email validates_confirmation_of: password validates_format_of: email ,: with => / ^ ([* @ \ S ++) @ ((? ::::::::::::: - Message = & gt; "Invalid Email" validates_acceptance_of: terms_of_service ,: message = & gt; "to create an account Our Terms of Service must agree "

Controller 

  Class UserController  "Success" and render: Action => Signup & End End

Edit: I have updated my code for some reasons. Now I can not create user. This will give me errors How does anyone go around this?

administrator 

  & lt;% form_for: user, @user ,: Url = & gt; The form changes in {: Action = & gt; "Signup"}. F | & Gt%;

This can also work

Then change the form accordingly: 

  & lt;% = f.label (: first, "first name")% & gt; & Lt;% = f.text_field: First% & gt;

Then add F and delete _tag on each one.

And the wrong part of it: 

  & lt;% = f.error_messages: header = & gt; "Please complete all fields" ,: message = & gt; "One or more fields"%> There is a problem in this

Not sure about: Header and: This is the work of the message in the last one, but I hope you get this idea.

Form tags have been updated, because they have a bug.

Eclipse CDT variable colors in editor -

I hope this is a good question to ask here. This programming is related, so I thought it would be better than the superuser, so I am using the CDT C ++ Eclipse plugin. I know how the editor changes colors for some things But is there a way to do that all the variables are different colors? For example in KDEValue, it sets the local variables and square variables in different colors and bold square squares. Can I copy it to CDT? Eclips provides some level of color customization for text editor syntax You can see it on the following: There are many elements, including the Window> Preferences> C / C ++> Editor> Syntax color code that can be changed, assembly, Comments, Preprocessor and Doxian Under the code, it is possible to change the color of some variable types, such as global variables, local variable announcements, local variable references, and parameter variables. But I do not think the code is capable of changing the color of each variable declared....
