Category and Subcategory and Resources are three different Models. Category is (currently) one of five titles (with an associated photograph).
Category hasMany subcategories, Subcategory belongsTo Category, Resources hasAndBelongsToMany Subcategories. To keep things simple for our user, they will be entering at the Category level, clicking on the title which passes the ID of the category then filters the next page, the Subcategories are only displayed if they belong to the clicked on Category. They also have the option, of seeing a complete, unfiltered list at any stage (most useful in resources). What I am trying to do (in every instance, but Edit is the one I started with that I cannot get to work) is always show the user which category (and eventually when looking at Subcategories which subcategory) they are in and when they finish viewing or editing, are returned to a filtered list. To do this each method of the subcategory and category classes pass around the ID of the current whatever, to enable the filtering… Or that's the idea. The code above is the edit method from Subcategory. So in reply to: Krissy - I'm using categoryID to grab the category title from the Category model in the first part of the function. It works. Setting the variable there allows me to see it in the edit view. Cricket - as in my reply to Krissy, the bit of code I use to display the category title using the categoryID is functional, yet also my debugging code. Knowing that that is working, do you still think routing could be the trouble? Jeremy - thanks for your help before and thanks again now. Has this made the issue clearer?
