Just added a new comment feature to my rails app and stumbled upon this issue. I'm getting a NoMethodError in Pics#show which comes from my _comment.html.haml partial.
I can see the comment thread on my show page but after I post the comment I'm getting this. Can go back to uncommented pics, but can't go to the ones I've already commented on.
I've been staring at the code for a while now and I need a fresh pair of eyes.

Everything is fixed now and working properly. Had to pass the #pic variable. Thanks

I have a custom method to update a join table row that used to work and is for some reason errorlessly-failing.
The app is a basic course portal with courses and lessons joined by lesson_completions, which have user_ids, lesson_ids, and a boolean value for complete.
The link I'm using looks like this:
<% if #lesson_completion.complete %>
<td class="pr-1"><%= link_to "<i class='far fa-check-square'></i>".html_safe, uncomplete_lesson_path(#lesson), method: :post, class: "text-red" %></td>
<td><%= link_to "Mark as Unfinished".html_safe, uncomplete_lesson_path(#lesson), method: :post, class: "text-red" %></td>
<% else %>
<td class="pr-1"><%= link_to "<i class='far fa-square'></i>".html_safe, complete_lesson_path(#lesson), method: :post, class: "text-red" %></td>
<td><%= link_to "Mark Lesson as Completed".html_safe, complete_lesson_path(#lesson), method: :post, class: "text-red" %></td>
<% end %>
The methods are in my lesson_completion_controller:
def complete_lesson
#lesson_completion = LessonCompletion.find(params[:id])
if #lesson_completion.update_attributes(complete: true)
redirect_to course_module_path(CourseModule.find(Lesson.find(#lesson_completion.lesson_id).id))
flash[:notice] = "Congratulations on completing that lesson!"
else
redirect_to lesson_path(Lesson.find(#lesson_completion.lesson_id))
flash[:warning] = "Oops! Something went wrong!"
end
end
def uncomplete_lesson
#lesson_completion = LessonCompletion.find(params[:id])
if #lesson_completion.update_attributes(complete: false)
redirect_to lesson_path(Lesson.find(#lesson_completion.lesson_id))
flash[:notice] = "Congratulations on completing that lesson!"
else
redirect_to lesson_path(Lesson.find(#lesson_completion.lesson_id))
flash[:warning] = "Oops! Something went wrong!"
end
end
If I use a debugger and look at the value for #lesson_completion on that page it confirms the correct user_id and lesson_id values.
My routes look like this:
post "lesson_completion/:id/complete_lesson" => "lesson_completion#complete_lesson", as: "complete_lesson"
post "lesson_completion/:id/uncomplete_lesson" => "lesson_completion#uncomplete_lesson", as: "uncomplete_lesson"
When I click the button, the server log shows no errors:

I want to implement a way of clicking a button and running a method without having to switch to the view of the specifid item/object found by id. I'm using PostgrSQL.
In my PaymentsController I have a method called withdraw, which looks something like this:
def withdraw
#payment = Payment.find(params[:id])
#payment.withdrawn = true
#payment.amount_interest = withdraw.amount * 1.1
#payment.save
head :ok
end
And the route:
patch '/withdraw/:id', to: 'payments#withdraw', as: :withdraw
each statement with link_to:
<% #payments.each do |withdraw| %>
<tr>
<td><%= withdraw.amount %></td>
<td><%= link_to 'Withdraw', withdraw_path(withdraw), method: :patch, remote: true %></td>
</tr>
<% end %>
EDIT: Upon clicking "Withdraw" I get an unending database query that looks like this:

My Payments model has the following:
account:string amount:decimal paid:boolean withdrawn:boolean amount_interest:decimal
belongs_to :member
Any assistance will be greatly appreciated.
The issue was a bug in my withdraw method.
changed:
#payment.amount_interest = withdraw.amount * 1.1
to:
#payment.amount_interest = #payment.amount * 1.1
I get an error of 'Name can't be blank' and "Name only allows letters, numbers and '-'" when trying to update a name. This was working fine but I have just gone through it again while writing a test for it and realise it isn't working anymore, I can't figure out why or what has changed to break it.

You need to add error_messages helper tag in the partial. That handles all error messages and show it properly.
It looks like your database has an existing record with the same name. Try inputting a unique name in. In your model, it is checking for :uniqueness.
I'm running into an issue where I rander a partial using AJAX and for some reason the line_items renders to the amount of products in it. So if there's 2 products, it loops through all line_items 2 times, causing it to be 4 elements listed instead of 2. So the loop keeps going by the amount of products in the line_items.
In my create.js.erb I have:
$('#shopping-cart').html("<%= escape_javascript render(#cart) %>");
and my _cart:
<div id="shopping-cart">
<div id="shopping-cart-header">
</div>
<div id="shopping-cart-items">
<table>
<%= render cart.line_items %>
<tr class="total-line">
<td colspan="2">Total</td>
<td class="total-cell"><%= number_to_currency(cart.total_price, unit: '') %></td>
</tr>
</table>
<%= button_to 'Empty cart', cart, method: :delete %>
</div>
<div id="shopping-cart-footer">
<%= link_to 'New order', new_order_path, class: 'btn btn-main btn-lg', data: { no_turbolink: true } %>
</div>
</div>
and the issues is with render cart.line_items I guess:
<% #cart.line_items.each do |item| %>
<% if line_item == #current_item %>
<tr id="current-item">
<% else %>
<tr>
<% end %>
<td><%= item.quantity %> ×</td>
<td>
<p><%= item.product.name %></p>
<% if item.line_item_attributes.exists? %>
<% item.line_item_attributes.each do |attribute| %>
<i><%= attribute.product_attribute.name %></i>
<% end %>
<% end %>
</td>
<td class="item-price"><%= number_to_currency(item.total_price, unit: '') %></td>
</tr>
<% end %>
if I've now added 2 products they're shown twice like this:
1 × red shirt 490.00
1 × blue shirt 89.00
1 × red shirt 490.00
1 × blue shirt 89.00
Total 579.00
Any one know what's going on? My logs are:

It seems that _line_items are rendered, and then _cart (which again contains line_items) are rendered - maybe thats an issue?
You're correct. When you call render cart.line_items, you're rendering a collection. To quote the Rails documentation,
When you pass a collection to a partial via the :collection option, the partial will be inserted once for each member in the collection:
<h1>Products</h1>
<%= render partial: "product", collection: #products %>
(this is the same as your render cart.line_items)
And then in the partial you will have access to a product (or line_item in your case) local variable, like this:
<p>Product Name: <%= product.name %></p>
So: Rewrite your partial view to represent a single line_item with a corresponding line_item variable instead of a collection.
