impressionist | Visual 3D editor for creating stunning impress | Editor library

I am looking to have two custom attributes for products, where the second custom attribute has unique options depending on the first attribute selected.

My particular circumstance is selling art that will have many different formats and sizes, where the price of the sizes will be different depending on which format is selected (IE: Print, Framed, Canvas, etc.).

The obvious alternative is to just have different product listings for each format, and not have the double drop down menu's. However, that is not ideally what I am looking to do.

This is the code provided in the documentation for a single select box and custom attribute:

Greetings NLP Experts,

I am using the Stanford CoreNLP software package to produce constituency parses, using the most recent version (3.9.2) of the English language models JAR, downloaded from the CoreNLP Download page. I access the parser via the Python interface from the NLTK module nltk.parse.corenlp. Here is a snippet from the top of my main module:

I'm currently building my first API with Grape and the Rails 5 api mode and it's going fairly well until now. I decided to install the Impressionist gem to be able to log the view counts of a certain model (future "popular" page) but I'm running into an issue where I feel I have setup the gem correctly but the impressionist method used to actually log the info in the database is undefined.

In my model, the gem is initialized like this is_impressionable :counter_cache => true

I then have in app/api/my_app/my_model.rb

I know this is hard but ... I am trying to count views for impressionist gem on a specific time from date of last post till time.now and the code below doesn't seem to work as this message appear ?

wrong number of arguments (given 0, expected 1..2)

I'm trying to setup multiple tagging in my app. I have used a single tag and tagging model which works fine for tagging a single model.

However, after setting up the association, i got this error when i wanted to create a new question undefined method map for nil:NilClass which actually points to <%= select_tag(:kategory_id, options_for_select(@kategories), :prompt => "Select Category", class: "form-control") %>. I don't know why it's pointing to this since it has nothing to do with the tagging. I might have made a mistake somewhere which i could not figure out.

Here is how i do the setup.

I added taggable_id and taggable_type to taggings table.
