问题 I am using sinatra 1.4.3 and mongoid 3.1.4.

I have still problem with will_paginate helper. In my views I get errors like: NoMethodError: undefined method `will_paginate' for #

Simple way to cache twitter gem tweet in Sinatra?

由 a 夏天 提交于 2019-12-08 08:35:22
I'm running into API Limit Requests which end up blowing my site up. Right now to avoid that I have the tweet request from the Twitter gem in a rescue block that returns a default string if something bad happens. I'm wondering what would be the best way to cache the latest tweet simply using: @twitter = Twitter.user_timeline("some_user", :include_rts => 1, :count => 1).first In case the API limit is hit? I use memcache (or now dalli ) for stuff like that. There are two options. You could hit the cache first and if the timestamp is within a certain threshold, just return the cached value

问题 Greetings, Every time I make a change to a Sinatra app I'm working on and try to refresh the browser (located at http://localhost:4567/) the browser will refresh and, the console window seems to restart the WEB brick server. The problem is that the content in the browser window does not change. A friend of mine told me it was a shotgun issue and referred me to rtomayko's shotgun gem: http://github.com/rtomayko/shotgun On this page I read that the shotgun gem would basically solve my problem,

问题 Presumably, not a whole lot of configuration is required - docs. The gem doesn't seem to work.

how can I use like query in ruby with sinatra?

由 依然范特西╮ 提交于 2019-12-08 04:11:32
问题 Here's the query I tried: @blogs = DB[:blogs].where(:title => params[:s_txt]).reverse_order(:id) In this query, I'd like to find blogs in my database. I also need to create a query that gives users more results. How can I do this? 回答1: I also had this problem and only found this solution @blogs = DB[:blogs].where("title LIKE '%#{params[:s_txt]}%'").reverse_order(:id) Curious if there are better ways.. Searching in two fields is repeating the LIKE and seperating by AND or OR @blogs = DB[:blogs

How do I get an array of check boxes in haml?

由 会有一股神秘感。 提交于 2019-12-08 04:02:23
问题 I have an array of strings, called @theModels, in a routine implemented as part of a Sinatra server. These models are options for the user to select, and are obtained by the back end (the idea being, as new models are added, then the front end code should not change). I'm using haml to render html. How can I enumerate each element in the list of @theModels such that each element is a checkbox? And how can I obtain which checkboxes the user has selected? I see that just putting = @theModels

Rack::ResponseHeaders in rackup for Sinatra

由 血红的双手。 提交于 2019-12-08 03:52:34
问题 I think this is a very easy one, but I can't seem to get it right. Basically, I'm trying to use Rack middleware to set a default Cache-Control header into all responses served by my Sinatra app. It looks like Rack::ResponseHeaders should be able to do exactly what I need, but I get an error when attempting to use the syntax demonstrated here in my rackup file: use Rack::ResponseHeaders do |headers| headers['X-Foo'] = 'bar' headers.delete('X-Baz') end I was able to get Rack::Cache to work
