Nov 09, 2017  Hi. Have a new server setup since a couple of days, using AD Authentication for the Users. We have the users in one OU, which i have configured in the ldap main settings in the gitlab.rb file. We have two mail domains for our users, most users have xxx@xxx.com for their primary smtp, the others have xxx@xxx.de for their primary smtp. Now when they try to logon, it’s working for users with. Apr 11, 2016 Model A has attribute 'languages', which is an array contains element such as 'English', 'French'. My site has a form which allows user to select a language and it will display all object whose 'languages' includes that language. Jan 13, 2015  NoMethodError: undefined method `gsub' for nil:NilClass following net-ssh patch upgrade #263. Closed esciara opened this issue Jan 13, 2015 13 comments. The NoMethodError: undefined method 'gsub' for nil:NilClass is somewhat cryptic and has made it difficult to find the origin of the problem (see discussion here.

If your error looks like ..

.. this means that you're calling a method on an object that has not been defined properly.

Step 1: Check return value of method you're is what you expect

Check to see what the return value of the method you're calling is. Is the return value the object you expect? You may need to handle a situation where you receive an false or nil value back.

For example, here we're searching for a contact by an id number that does not exist:

The error:

We expected contact to be defined, but as the contact wasn't found, we couldn't call the method full_name on it.

To fix this error, we could adjust our program like so:

Step 2: Define instance variables before using them

Unlike local variables, which when undefined, raise an undefined local variable error, instance variables start out as a NilClass, and you won't receive a helpful undefined variable style message. Instead, you'll only learn about the issue when you try to call a method on them.

For example, here we're trying to determine someones age by the current year and the year they were born:

Our error:

@current_year was never defined, and as @current_year begins with an @, it is treated as an instance variable. Ruby was expecting that NilClass had a method called - (the subtraction symbol). In other words, the ruby interpreter expected this:

Ruby Nilclass

Of course, we wouldn't add a method like this to NilClass in this way.

What we need to do is define @current_year first:
