Hello, I am using rails 1.0 and I have following questions. Please help me. [1] How can I do logging in the rails models? I checked the wiki but didn’t find anything which I explained how to do logging in models. [2] Say I have a certain model, when I declare a function in the model, and try to use that function from a view or a unit test, I get an error. For views the error occurs only once during the first execution but for unit tests it is repeatable. model file: class MyModel \< ActiveRecord::Base def abc “ok” end end view file: \<%= @mymodel.abc %\> What am I doing wrong? Is it something strange and unexpected? [3] During testing, if I have a fixture file called products.yml and some named entries in it, I get an error if I try to use those named entries as variable named in my unit tests. The agile book says: “Each named fixture is also automatically ?found? using an Active Record finder method and put in an instance variable named for the fixture.” But when I am trying to repeat this I am getting errors, am I missing something or doing something wrong or have other people also experience the same problem? Thanks. – Surendra S.

Use following statement: RAILS\_DEFAULT\_LOGGER.info “This will be logged with ‘info’ level” But please not use it in your models. Rather, use it in your tests. Then even if you forgot to remove logging statements they will not have impact on performance or log size of your application. > [2] Say I have a certain model, when I declare a function in the model, and > try to use that function from a view or a unit test, I get an error.

From Rails 0.14 and onwards fixtures are no longer put in instance variables. You should either use: fixtures :users users(:bob) or modify the file test/test\_helper.rb and change value of self.use\_instantiated\_fixtures to true. Second method will slow down tests (in case of large fixture sets considerably). ---

While writing unit tests for a model, I noticed that I am not able to use the methods generated by different associations. How do I use and test them? Thanks once again. – Surendra S.
