Modifying a SQL query for use with 'will_paginate' in Ruby -


I have the following SQL query that I use to get some lines from a MySQL database: 

  SELECT code_ver, the result from the MasterState, where the date & gt; = DATE_SUB (CURDATE (), INTERVAL 90 days) Order by DESC;   
 This query gives me data from the last 90 days. Now I want to display 10 days of data at once in my html.erb page (view). I know that paging can be calculated using 'will_pignet' and 'camineri' gems. But I'm not sure how to ask the database with some of the above mentioned conditions.  
 Can anyone help me with the code here?   
 
 
 It is such that you can create it in ActiveRecord:  
  Mastertest.where ('date' =? ', Time.Now-90 ("Code_ver, Results")   
 From here, you can either either chain or fighter Methods, or if you want, do your roll. You can roll the question in class system if you use a lot of it:  
  class Mastertest def self.last_90_days where ('Date' =? ', Time.now - 90 DAS). Order (' Date DESC '). Select ("Code_V , Result ") end ## Here is an example of a simple page: def self.page (page, per page) limit (per page) .offet ((page - 1) * Per_page) end-end Mastertest.last_90_days.page (1 , 20) # = & gt; [...]

Python SQLAlchemy：AttributeError: Neither 'Column' object nor 'Comparator' object has an attribute 'schema' -

I tried to create a new database in my project, but when I run the script, I get this error, I have another project, this type of definition worked before, but now it gets a single error. I am using Python 2.7.8 and the version of SQLAlchemy module is 0.9.8. By the way, using a project flask- SQLAlchemy, it works well, I'm confused.

mongodb - CakePHP paginator ignoring order, but only for certain values -

While pagging my user model in kppp, I can sort with some values, but not others. For example, I can order results from created or email , for example, but username or reputation seems to come back order by arbitrary command for example with a list of users: $ this-> paginate = array ('condition' => array ( 'User.is_active' = & gt; true), 'border' => 24, 'order' => array ('User.created' => DESC)); Works as expected, but $ this - & gt; Paged = array ('conditions' = & gt; array (' user.isIactive '= & gt; true),' border '= & gt; 24,' command '= & gt; array (' user repeats' = ' & Gt; DESC ')); No, no. I first thought that this could be a database issue, but when I search the database directly, sorted as expected. Note: I am using Mangodebi with the Mongo DB plugin of Ichikawa for the KPPHP; Pagnetizing users are used to work properl...
