  1. POaccessing deeply nested params rails
    text
    copied!<p>I am writing a piece of code in my controller that is suposed to take the data a user inputs in the form of 00:00 and convert that into minutes before sending it to the model. The code I am using is pretty simple, just split the :duration parameter at the colon and multiply hours by 60 and add the minutes to that number. When I submit the for I get an error when it tries to perform split on a nil object. This must mean I am not accessing the parameter correctly but I am confused as to how I would navigate to a deeply nested parameter and cant seem to find any documentation regarding deeply nested parameters. </p> <p>Here is my model organization:</p> <pre><code>log_entry &gt;&gt; has many workouts &gt;&gt; has many workout_times, which has :duration as an attribute </code></pre> <p>This is the code within my log_entries_controller:</p> <pre><code>def convert_duration hours, minutes = params[:log_entry][:workout][:workout_time][:duration].split(":") params[:log_entry][:workout][:workout_time][:duration] = (hours.to_i * 60 + minutes.to_i) end </code></pre> <p>I have tried all the ways I could think of to write the params part but I cants seem to get it right. I am pretty new to rails/programming so there might be somthing totally obvious I am missing...</p> <p>EDIT</p> <p>Here is the log info of parameters past: </p> <pre><code>Parameters: { "commit" =&gt; "Save", "log_entry" =&gt; { "date(1i)" =&gt; "2011", "date(2i)" =&gt; "10", "date(3i)" =&gt; "13", "workouts_attributes" =&gt; { "0" =&gt; { "time_of_day" =&gt; "AM", "summary" =&gt; "", "workout_times_attributes" =&gt; { "0" =&gt; { "duration" =&gt; "2:00", "zone" =&gt; "1", "_destroy" =&gt; "false" } } } } }, "authenticity_token"=&gt;"zD6qS6jOSQ3/mRyH7RAgAzWYmwHub0+uBG1sjPVvkEY=", "utf8"=&gt;"\342\234\223" } </code></pre>
