Question

I’m using datamapper to store to a database. immediately after the db is migrated none of the methods exist because there are no values

<input type="text" name="seed" value="<%= @seed.value unless @seed.respond_to(value)? %>"

Answer 1

I’m not too sure I follow your question, but it looks like this:

@seed.value unless @seed.respond_to(value)?

Should be this:

@seed.value if @seed.respond_to?(:value)

respond_to? is the name of the method, so put the question mark in the correct place. Also, you want to pass a Symbol :value rather than the variable/method call value as the argument.

Finally, that should be if, not unless.
