Check for Duplicates in a Database Before Entering Data
- by gamerzfuse
Before Entering data into a database, I just want to check that the database doesn't have the same username in the database already. I have the username in SQL set as a key, so it can't be duplicated on that end, but I am looking at finding a more user-friendly error message then "KEY already exists". Is there are simple way to check if the variable value already exists in a row? Thanks!Read the article

auto submit form from command line
- by combatwombat
I have a form page in PHP that reads a DBF, and conditionally converts it into a MySQL - extracting the data from an old, but still production accounting app. The conversion should be able to be actioned without user intervention, ie scripted from the web-host's command line on a cron job. How can I get PHP to submit the form automatically when receiving variables at command line, like for instance a specific post variable? Every auto-submit I've found so far relied upon javascript, which would be useless at PHP command line.Read the article

All possible permutations of a set of lists in Python
- by Ian Davis
In Python I have a list of n lists, each with a variable number of elements. How can I create a single list containing all the possible permutations: For example [ [ a, b, c], [d], [e, f] ] I want [ [a, d, e] , [a, d, f], [b, d, e], [b, d, f], [c, d, e], [c, d, f] ] Note I don't know n in advance. I thought itertools.product would be the right approach but it requires me to know the number of arguments in advanceRead the article

How to add a context processor from a Django app
- by Edan Maor
Say I'm writing a Django app, and all the templates in the app require a certain variable. The "classic" way to deal with this, afaik, is to write a context processor and add it to TEMPLATE_CONTEXT_PROCESSORS in the settings.py. My question is, is this the right way to do it, considering that apps are supposed to be "independent" from the actual project using them? In other words, when deploying that app to a new project, is there any way to avoid the project having to explicitly mess around with its settings?Read the article

GLOBALS ARE BAAAAAAADDDD!!!!!

Ruby - How to remove a setter on an object
- by Markus Orrelly
Given a class like this: class B class << self attr_accessor :var end end Suppose I can't modify the original source code of class B. How might I go about removing the setter on the class variable var? I've tried using something like B.send("unset_method", "var="), but that doesn't work (nor does remove_method, or overwriting that method with a var= method that doesn't do anything). Any ideas?Read the article
