Posted in Form Objects Design Pattern Discussion

Your comment emphasizes the use of Form Objects Design Pattern in various applications. He highlights a preference for checking validity using "@contact_form.valid?" before sending mail. This ensures that the contact form's state is appropriate, even though it doesn't save anything. This approach enhances code clarity and allows for different "valid" states, adhering to a more versatile design pattern. It's a good example of leveraging design patterns for more maintainable and understandable code.

Hi GoRails Community,

I'm working on a Rails project that involves complex nested attributes, and I've hit a roadblock. I want to efficiently manage parent-child relationships within my models, but I'm struggling to figure out the most Rails-idiomatic way to do this.

Specifically, I'm trying to understand how to utilize the accepts_nested_attributes_for method in conjunction with strong parameters to allow certain attributes to be updated. I've scoured the documentation but haven't found a clear example that fits my case.

Has anyone here dealt with a similar situation, or could you point me to a resource or tutorial that covers this topic in depth? Any insights or code snippets would be greatly appreciated!

Thanks in advance!

Posted in How to work with nested methods correctly

Certainly! You can modify your namespace method to take the parent path as an argument and concatenate it with the current path. Here's a solution:

def namespace(path, parent_path = "", &block)
full_path = [parent_path, path].reject(&:empty?).join('/')
(@namespaces ||= []) << full_path
instance_exec(full_path, &block) if block_given?

namespace "top" do |top_path|
namespace "middle", top_path do |middle_path|
namespace "bottom", middle_path

puts @namespaces

This code uses the instance_exec method to pass the concatenated path to the next level of the block, which helps you create the desired @namespaces array.

Posted in How do I have a list view like tailwind?

It seems like the layout issue you're facing might be related to the CSS styling of your list. You can try altering the CSS to display the listings in rows rather than as large boxes. If you're using a table, ensure each listing is within a table row or, if using divs, apply a style like display: flex; flex-direction: row; to the container. Inspecting the example's code to identify the differences in styling can also provide clues to achieve the desired layout. If necessary, consulting a front-end developer can be a quick way to resolve the issue.
