hi all, i am getting an error ‘undefined method ‘current’ for 852:Fixnum’, the error coming for following line

<%if @expert_pagination.current.previous%> <%else%> <%end%>

can anyone know why it is coming ? i am using Ruby 1.8.6,rails :2.3.11 and gem 1.6.2

....and the value of @expert_pagination is what? Have you debugged it to see? I assume you expect it to be an object of some sort with a method ".current"; but the error is telling you that it's a Fixnum...

3

yes the @expert_pagination is object one more condition is there as same above ‘@book_pages.current.previous’ here it is getting the value in number (1,2,3,4)

here also it is given same error.

yes the @expert_pagination is object

No it is not an object, it is a number. Have a look at the Rails Guide on Debugging to get ideas on how to work out what is going on.

yes it is number ,but when the number is like 6,7 it is giving an error ‘‘undefined method ‘current’ for 852:Fixnum’’

I don't understand what you are saying, you accept that @expert_pagination is a number, but then expect to be able to say @expert_pagination.current. A number does not have a method current so the error is shown. What do you expect @expert_pagination.current to do if @expert_pagination is a simple number?

I also don't understand what you mean by "when the number is like 6,7" 6,7 is not a number, or do you mean 6.7?

Have you followed my earlier suggestion to read the Rails Guide on debugging in order to find out what is going on? Please answer this question if you reply, do not just ignore it.

colin, i am new to ROR ,the scenario is like that if goto Url www.sugestica.com:8881 and in search on home page if searched using latest suggestions it will give

me error and also i said before that the error is coming for ‘@book_pages.current. previous’ which is getting the value from controller.i debug and found that it getting value number single digit 6

suppose .

i think now you are clear what i am asking for.I just want to know the cause of this error undefined method `current’ for 6:Fixnum

Yes, the error is (as has been said several times already) that something you think should be an object with the method .current, is actually a number "6"... look at where you populate @book_pages.

The cause of the error is simple. 1. @book_pages is the number 6. 2. You have the code @book_pages.current 3. This is the same as saying 6.current 4. The number 6 does not have a method called current 5. Therefore there is the error that the method 'current' is not defined for the number 6.

Now if your question is 'why is @book_pages the number 6' then you must look at the code where you setup @book_pages.

I think you would be better to work through some tutorials first however. I suggest that you forget what you are doing for a few days and work right through something like railstutorial.org, which is free to use online. Then you will have a better grasp of the fundamentals of RoR and will be able to answer your own questions.
