  • Advice on creating admin panel where user can upload, remove and order the files

    - by Manoj
    I'm working on a website where a logged-in admin needs the ability to upload and manage multiple PDFs from their computer. They'd need to be able to upload/remove the files. Also, there would need to be a way that they can sort the list of uploaded files and save that order so that other visitors to the page would see the list of files in that particular order. I looked into jQuery Uploadify among other things. Would javascript be the right way to go? Thanks, Manoj

  • MySQL ORDER BY date and team

    - by Michael
    I would like to order by date and then team in a MySQL query. It should be something similar to this: SELECT * FROM games ORDER BY gamedate ASC, team_id AND it should output something like this: 2010-04-12 10:20 Game 1 Team 1 2010-04-12 11:00 Game 3 Team 1 2010-04-12 10:30 Game 2 Team 2 2010-04-14 10:00 Game 4 Team 1 So that Team 1 is under each other on the same date, but separate on a new date

Anyone knows how to setup tomcat 5.5 to deploy wars on restart in an specific order? Thanks in advance

  • Rails. Putting update logic in your migrations

    - by Daniel Abrahamsson
    A couple of times I've been in the situation where I've wanted to refactor the design of some model and have ended up putting update logic in migrations. However, as far as I've understood, this is not good practice (especially since you are encouraged to use your schema file for deployment, and not your migrations). How do you deal with these kind of problems? To clearify what I mean, say I have a User model. Since I thought there would only be two kinds of users, namely a "normal" user and an administrator, I chose to use a simple boolean field telling whether the user was an adminstrator or not. However, after I while I figured I needed some third kind of user, perhaps a moderator or something similar. In this case I add a UserType model (and the corresponding migration), and a second migration for removing the "admin" flag from the user table. And here comes the problem. In the "add_user_type_to_users" migration I have to map the admin flag value to a user type. Additionally, in order to do this, the user types have to exist, meaning I can not use the seeds file, but rather create the user types in the migration (also considered bad practice). Here comes some fictional code representing the situation: class CreateUserTypes < ActiveRecord::Migration def self.up create_table :user_types do |t| t.string :name, :nil => false, :unique => true end #Create basic types (can not put in seed, because of future migration dependency) UserType.create!(:name => "BASIC") UserType.create!(:name => "MODERATOR") UserType.create!(:name => "ADMINISTRATOR") end def self.down drop_table :user_types end end class AddTypeIdToUsers < ActiveRecord::Migration def self.up add_column :users, :type_id, :integer #Determine type via the admin flag basic = UserType.find_by_name("BASIC") admin = UserType.find_by_name("ADMINISTRATOR") User.all.each {|u| u.update_attribute(:type_id, (u.admin?) ? admin.id : basic.id)} #Remove the admin flag remove_column :users, :admin #Add foreign key execute "alter table users add constraint fk_user_type_id foreign key (type_id) references user_types (id)" end def self.down #Re-add the admin flag add_column :users, :admin, :boolean, :default => false #Reset the admin flag (this is the problematic update code) admin = UserType.find_by_name("ADMINISTRATOR") execute "update users set admin=true where type_id=#{admin.id}" #Remove foreign key constraint execute "alter table users drop foreign key fk_user_type_id" #Drop the type_id column remove_column :users, :type_id end end As you can see there are two problematic parts. First the row creation part in the first model, which is necessary if I would like to run all migrations in a row, then the "update" part in the second migration that maps the "admin" column to the "type_id" column. Any advice?

  • Does MySQL short-circuit the ORDER BY clause?

    - by nickf
    Given this SQL: SELECT * FROM mytable ORDER BY mycolumn, RAND() Assuming that mycolumn happens to only contain unique values (and hence, contains enough information to perform the ORDER BY), does MySQL short-circuit the operation and skip evaluating the rest?

  • What is the 'order' of a perceptron

    - by Martin
    A few simple marks for those who know the answer. I'm doing revision for exams at the moment and one of the past questions is: What is meant by the order of a perceptron? I can't find any information about this in my lecture notes, and even google seems at a loss. My guess is that the order is the number of layers in a neural network, but this doesn't seem quite right.
