You have a app/views/register/signup.html.erb view and Rails expects signup method in your registrations_controller and is looking for #owner
instance method but you don't have signup method that's why it's raising an error because #owner is nil.
def signup
#owner = Owner.new(owner_params)
...

I’m having trouble with ordering my houses. I have a houses that belong_to category (category has_many houses) and I want to order the houses on the index based on their category_id, but whatever I try it doesn’t seem to change the order. It’s a mystery to me. Maybe you could help me out?

#houses = params.has_key?(:h) ? index_result(#houses) : #houses

wall_thickness = params[:h].to_i
if wall_thickness == 1
houses.order(:name)

houses = houses.where(:wall => wall_thickness)

This is the index where the houses are filtered based on their wall thickness (see in app/controllers/houses_controller.rb ). This is where I want the house to order based on their category_id, which doesn’t work at the moment.

As you can see, there's a lot of duplication of code (not very DRY) and so I'd like a little help in getting more DRY and have the houses be ordered by category_id and then by price.
I'd appreciate your help.
It's not clear to me what you tried so far, but if all you need is to sort by category_id, I think you can define a scope within your house model as follow:
scope :sort_by_category_id_asc, ->{
order(arel_table[:category_id].asc)
}
Then you can use that scope as follow: House.where(...).sort_by_category_id_asc, also you can use desc, depends on how you want to order the result.
Hope this helps! 👍
I created a method that can sort houses by its category_id. If you want to sort it by other things just change category_id to your desired thing. You can sort it ascending or descending order. Here it is:
def sort_by_category_id(houses, order)
case order_by
when "asc"
houses = houses.sort_by{ |house|
house[:category_id]
}
when "desc"
house= house.sort_by{ |house|
house[:category_id]
}.reverse!
end
house
end
Don't forget to call this method wherever you want it to be worked. Below code will sort your houses by category_id and save it in sorted_houses variable. I
sorted_houses_asc = sort_by_category_id(#houses, "asc")
sorted_houses_desc = sort_by_category_id(#houses, "desc")
Hope this helped you somehow.
I have two tabs at the profile page: tab 1) my recipes, tab 2) my favorites.
Kaminari pagination works just fine when I go to the index page for recipes. However the pagination does not work properly at the profile page. When I click on next it does show me the next page, but the pagination bar disappears. So I cannot go back, unless I refresh the page.
Who can help me? Thank you in advance.

<script>
var addpic = function(id) {
var el = '#picture' + id;
$(el).removeClass('hidden');
}
$('.reply').on('click', function(e){
e.preventDefault();
$(this).next().removeClass('hidden');
});
</script>
Figured out the issue, JS was preventing the default for all clicks inside a .reply div. Had reply used in the wrapper for the reply form, so it was preventing the default. Got it working now by changing the class of the reply link to 'addreply' and the js listener to 'addreply' as well.

You should use kaminari or will_paginate gem...
Kaminari example:
Gemfile:
gem 'kaminari'
bash:
bundle
rails g kaminari:views default
products_controller.rb:
#products = Product.order("name").page(params[:page]).per(5)
config/locales/en.yml:
en:
hello: "Hello world"
views:
pagination:
previous: "< Previous"
next: "Next >"
truncate: "..."
products/index.html.erb:
<%= paginate #products %>
app/views/kaminari/_prev_span.html.erb
<span class="prev disabled"><%= raw(t 'views.pagination.previous') %></span>
Will_paginate example:
