I have multiple fields for social networking websites where users can enter their username and it would link to their twitter, facebook, myspace account etc. My problem is how can I have it so when a user enters their username I can link to their account.
Here's what I have and I know this is probably not correct. In my profile index.html
<%= link_to twitter_url %>
profile helper method
def twitter_url
return(self.url= "http://twitter.com/#{profile.twitter}/account")
end
In my profile controller
include ProfilesHelper
The actual field in database is called
twitter_link
How can I get the just the user username then on my part which will do the rest link to their twitter, facebook etc account page?
How is that method supposed to know what the profile object is without you passing it in?
I'm imagining there being a #profile variable defined in your controller. In the view, you would have this:
<%= link_to twitter_url %>
And in the helper, this:
def twitter_url
"http://twitter.com/#{#profile.twitter_link}/account"
end
Note here that you don't need to set self.url or have an explicit return. This is because the method will automatically return a String which is what link_to takes.
If you want this method to be in a helper that's available in just your ProfileController, then why not put it inside ProfileHelper so that it's automatically included just by being related by name?

I want devise to redirect to specific controller index action( or specific page) after user is sign_up.
In detail, i have an app with 2 ways to sign-up : for the client and for the Professor . Actually, the 2 type use the same registration page, it works very nice but when they sign_up they are automatically redirect to the same page ...
So, i want to change the way like this :
- when user click on I want to become Professor i want to register (full name, mail, password) and redirect after sign_up to the Professor dashboard
- and when user click on Client i want to register with the "same way" BUT in the end, i want to redirect to the client's dashboard.
So, i started to change devise.rb to change this
config.allow_unconfirmed_access_for = 2.days (automatically login after sign_up)
And in my RegistrationsController, i override the after_sign_up_path_for to have something like
def after_sign_up_path_for(resource)
if 'user is Prof'
redirect_path_professor
else
redirect_path_client
end
end
but how can i check (in condition) if user click on Prof. or Client ?. Its the same resource (registration) ^^
Thanks
Why not using only one link, then let the user selects his role in the registration view?
If you really want two links for the same view, you should pass the role in a param (something link link_to 'Becoming a Professor', new_registration_path(role: 'professor'), then add an hidden_field in your registration form with the value of the param.
= f.input :role, as: :hidden, input_html: { value: params[:role] }
But don't forget to validate the content of the params to avoid the bad values sent by teasing users
Also, after_sign_in_path_for(resource) should be in application_controller. You'll need a column in users to specify the role, and your method will looks like something like this:
def after_sign_in_path_for(resource)
stored_location_for(resource) || (resource.role.professor? ? professor_dashboard_url : user_dashboard_url(resource))
end
I am building my first app using rails and i am struggling to give an account to each user. Its a simple app where a user creates a post and saves it. this post can be seen on index page. Until now we are ok. when i sign out, i register a new user and i log in. when i go to the index page, i can see what other user has saved. I want to have a private index page for each user where no one can see what users are saving in their app. I am using Gem 'Device" to authenticate my app, but i don't know how to make private their account? any ideas?
You have implemented authentication. Now you need to build authorization.
You have to define what data can be accessed by user.
Take a look at:
CanCanCan
With devise authentication technique, after logging in the user you can write a clean piece of code to render the posts of the logged in user. You can use session data to do it. the current_user helper method returns the model class relating to the signed in user. With devise, it ensures after authentication that, it has the helper methods ready to be used. So, the error with no such user with that id can be avoided.
#web/controller/post_controller.rb
before_filter :authenticate_user!
def list
#posts = current_user.posts
end
And then, use #posts in the list view to render the posts of the logged in user only.
<% #posts.each do |post| do%>
<%= post.content %>
<% end %>
In my Rails app I have a user model (Devise) with url_field for Twitter.
Right now I have this in my show page:
<%= link_to #deal.user.company_twitter, #deal.user.company_twitter, :class => "comp_twitter" %>
It shows the entire link in the show page (even http://), that's because my url_field makes the user add "http://" or it won't validate the link.
I want the user to only add their "#name" instead of the whole Twitter link when creating their profile. I would also want to show only the #name instead of the Twitter link in the "show" page. How can I do this?
Simply don't use an url_field, but a regular string database field, like twitter_username. When signing up, let the user enter their username, e.g. foo.
For getting the real URL to the Twitter account, create a new method in your user.rb model:
def twitter_url
"http://twitter.com/#{self.twitter_username}"
end
The advantage is that at this point, in your model, you can include a custom validation that would check if this URL really exists after the user has submitted their twitter_username.
Finally, use that in your view instead of just the URL:
<%= link_to "##{#user.twitter_username}", #user.twitter_url %>
This would render:
#foo
In my Rails 3 app, I have a model called User with id and username, both are indexed and unique. Somewhere in some views I have following:
<%= link_to 'Show this user', user %>
That creates a link like this:
Show this user
where that horrible number is the id (primary key). Now, for the SEFness of the site, I would like to use the username instead of the id wherever I use link_to "...", user, but only for that User model. Adding parameters to the link_to does not help, because I already have it in many places (and I do not want to have to add another parameter everywhere all the time).
How can I override the behavior of the link_to helper only for one model?
Here is a complete answer to this question, as I deducted from the accepted answer. I added following to my User model:
def to_param # overridden to use username as id, and not the id. More SEF.
username
end
def self.find(id)
#user = User.find_by_id(id)
#user = User.find_by_username(id) if #user == nil
throw ActiveRecord.RecordNotFound.new if #user == nil
#user
end
This now makes all links generated with link_to use the username, while the find will try both the id and the username, making it also backward compatible.
Thought someone as new as me to Rails would find this useful.
Not sure of what I'm saying, but overriding #to_param in your model may be what you're looking for.
I am currently reading a book, and learning ruby on rails. (Agile Web Development with Rails 4th Edition) .In the book it says how to write a simple product list and display it. I am modifying this idea, to create a user login system.
I am only working on the views now.
So I just need to make sure that my idea is right. My idea is:
The show.html file from the USER model, show data for one user. (given of course its ID)
for example : http://localhost:3000/users/980190974 will give me the html page for the current user right? Now I can allow the user to edit his/her information by using the
<%= link_to 'Edit', edit_user_path(#user) %> link or restrict him from viewing other users by removing the <%= link_to 'Back', users_path %> << that lists all the users from the database. But before the user views his/her details he must login, using his email and password. So by making an html page, that takes 2 strings (username, and password) searches my mySQL database and return the user ID , that I then use to "render" the user's HTML page.
Is my way of thinking correct? Or am I just completely irrelevant on how Ruby on Rails works? O_o
You are heading in the right direction. One thing to point out is that simply removing the link <%= link_to 'Back', users_path %> is not sufficient to avoid other users from accessing the /users path. In the (user) controller you have to use something like:
class UserController < ApplicationController
def index
unless current_user.is_admin
redirect_to user_path(current_user)
return
end
... rest of code here
end
end
where current_user could be a method returning the user object
