I wrote this library so I don’t have to keep track if I should use HttpRuntime.Cache, AppDomain.CurrentDomain.SetData, HttpContext.Current.Session, or a Dictionary…now I just use GlobalCache or UserCache. It also makes unit testing a webapp a snap, because if you use IGlobalCache/IUserCache in your code, you just inject the Windows-based cache in your unit test setup.
You can download the solution with dlls here: Universal Caching solution
A breaking change in ASP.NET 4.0 causes a javascript error to be thrown on a page if a query string has a “potentially unsafe” character, such as an apostrophe in a last name.
You’ll see the error (possibly only while debugging): “A potentially dangerous Request.QueryString value was detected from the client” when passing the special character in a query string in a button click or a jqgrid’s FillGrid postData BuildGrigArgs function.
The fix is easy: set the behavior back to ASP.NET 2.0 in the web.config with this line in the system.web section right below your </compilation> tag (the requestPathInvalidCharacters parameter here blocks everything except a single quote):
<httpRuntime requestPathInvalidCharacters="<,>,*,%,:,&,\" requestValidationMode="2.0" />
And in your pages be sure you don’t encode the parameter in the MVC code in your javascript (i.e. you’ll need to use <%= instead of <%: for those parameters that need special characters).
For example, this:
function BuildPreviousArgs() {
var args = new Object();
args.FilterLastName = "<%: Model.FilterLastName %>";
return $.param(args);
}
Has to be changed to this:
function BuildPreviousArgs() {
var args = new Object();
args.FilterLastName = "<%= Model.FilterLastName %>";
return $.param(args);
}
If you upgrade from MVC 1 to 2 or higher and your controller factory (such as StructureMapControllerFactory) throws a “no suitable method found to override” error for your GetControllerInstance method, be sure you have a reference to System.Web.Routing:
using System.Web.Routing;
And be sure you add the RequestContext parameter to the GetControllerInstance method call like this:
protected override IController GetControllerInstance(RequestContext requestContext, Type controllerType)
Make sure python is referenced in your Path: < my python path >\python.exe (where < my python path > is the directory where you installed python, such as "C:\Python26").
Make sure IPython is installed (from here: http://ipython.scipy.org/moin/Download)
Make sure PyReadline is installed (from here: https://launchpad.net/pyreadline/+download)
In Console2, right-click go to Edit –> Settings… –> Tabs Add new tab with
Title: iPython Icon: < my python path >\DLLs\py.ico Shell: cmd.exe /k "< my python path >\Scripts\ipython.py -p sh" Startup dir: C:\ (or wherever)
Hit ok and in your Console just go to File –> New Tab –> iPython and you’re off and running!
1. Create a directory for your project (e.g. “hello”). 2. In this directory, create a hello.py file with this code:
from flask import Flask
app = Flask(__name__)
@app.route("/")
def hello():
return "Hello World!"
if __name__ == "__main__":
app.run()
3. Download and install latest setuptools for your version of python.
4. Download latest flask, werkzeug, and jinja2, and decompress each in their own directory in your hello project like this:
hello
flask
jinja2
werkzeug
Note: Make sure the files are decompressed so the setup.py is in the root of each folder.
5. In the cmd shell for your hello project, run
easy_install Flask
6. Then
python hello.py
7. if all is well, you should see
* Running on http://127.0.0.1:5000/
8. Finally, you should see “Hello World!” in your browser at http://127.0.0.1:5000
