Stories with many tags, tags with many stories, has_and_belongs_to_many howto?
..."story", I want to add several tags to it. Then, the
model should create those tags and link them to the respective stories,
and for the tags that already exists, just link them to the story.
I tried something like this (snippets):
class Tag < ActiveRecord::Base
def self.create(taglist)
tags = Array.new
count = 0
taglist.split(/,/).each do |tag|
tags[count] = Tag.new(:name => tag.chop.downcase)
count += count
end
end
end
class StoriesController < ApplicationController
def create
@tags = Tag.create(params[:ta...

dygraphs, multiple graphs and shiny
...ackoverflow.com/questions/30509866/for-loop-over-dygraph-does-not-work-in-r
the solution to have the plot shown from a RNotebook is code like this:
> library(dygraphs)
> lungDeaths <- cbind(mdeaths, fdeaths)
> res <- lapply(1:2, function(i) dygraph(lungDeaths[, i]))
> htmltools::tagList(res)
and if you put that into an RNotebook and knit it, it works. Okay in order to have a reproducible example, I now try to create a Shiny App using that example, and the template generated by RStudio. To use dygraphs in Shiny, you replace the normal render and plot routines, such that the...

Need some brainstorming help: acts_as_taggable_list?
...lationships. There are
some good ideas about HABTM lists:
http://wiki.rubyonrails.org/rails/pages/HowToUseActsAsListWithHasAndBelongsToMany
But easily getting that to only show messages for a particular user is not
straightforward. You could hack it a bit by adding another table/model that
was a TagList, with a user_id, tag_id, message_id, and position - but that
seems like a lot of data duplication.
That just got me thinking that maybe you can make the model for TagList, but
not have it be based on an actual table (make it a composite model). I seem
to remember reading about that - maybe I'...

Return all rows, split then show uniques
...2. banana melon
3. apple peach lime
What I want to do with that data is use the .split method to divide them
into separate values in an array, then use the .uniq method to return a
unique list of the words like so:
apple, banana, pear, melon, peach, lime
So in my controller I have:
def taglist
@tags = Tag.chop_em(params[:tag])
end
and in my model I know I need something:
def self.chopem(tag)
Tag.find(:all)
end
I think I lack the understanding of how the array that comes back from
the database is constructed. Can anyone explain this so I can chop those
words up and sort them with t...
