  • how to use cherrpy built in data storage

    - by user291071
    Ok I have been reading the cherrypy documents for sometime and have not found a simple example yet. Let say I have a simple hello world site, how do I store data? Lets say I want to store a = 1, and b =2 to a dictionary using cherrypy. The config files are confusing as hell. Anyone have very simple example of storing values from a simple site in cherrypy?

  • Get Username from a Cookie

    - by craphunter
    Hi, I use the backend solution from django. I just want to get a username from the cookie or the session_key to get to know the user. How I can do it? from django.contrib.auth.models import User from django.contrib.sessions.models import Session def start(request, template_name="registration/my_account.html"): user_id = request.session.get('session_key') if user_id: name = request.user.username return render_to_response(template_name, locals()) else: return render_to_response('account/noauth.html') Only else is coming up. What am I doing wrong? Am I right then that authenticated means he is logged in? -- Okay this I got! Firstly, if you have some clarification to a question, update the question, don't post an answer or (even worse) another question, as you have done. Secondly, if the user is logged out, by definition he doesn't have a username. I mean the advantage of Cookies is to identify a user again. I just want to place his name on the webpage. Even if he is logged out. Or isnt't it possible?

  • nested list comprehension using intermediate result

    - by KentH
    I am trying to grok the output of a function which doesn't have the courtesy of setting a result code. I can tell it failed by the "error:" string which is mixed into the stderr stream, often in the middle of a different conversion status message. I have the following list comprehension which works, but scans for the "error:" string twice. Since it is only rescanning the actual error lines, it works fine, but it annoys me I can't figure out how to use a single scan. Here's the working code: errors = [e[e.find('error:'):] for e in err.splitlines() if 'error:' in e] The obvious (and wrong) way to simplify is to save the "find" result errors = [e[i:] for i in e.find('error:') if i != -1 for e in err.splitlines()] However, I get "UnboundLocalError: local variable 'e' referenced before assignment". Blindly reversing the 'for's in the comprehension also fails. How is this done? THanks. Kent

  • Preventing a security breach

    - by Wiz
    I am creating a website where you "post", and the form content is saved in a MySql database, and upon loading the page, is retrieved, similar to facebook. I construct all the posts and insert raw html into a template. The thing is, as I was testing, I noticed that I could write javascript or other HTML into the form and submit it, and upon reloading, the html or JS would treated as source code, not a post. I figured that some simple encoding would do the trick, but using is not working. Is there an efficient way to prevent this type of security hole?

Basically what I am trying to do is find out if the string is actual string or int or float.` if int( val_dict['val1'): dosomething else if float(val_dict['val1']): dosomething thanks

  • global applied stylesheet link on debian box

    - by James
    Hi there, Having some trouble identifying what is wrong with my link to an external CSS stylesheet... I am using a debian box to host some things... including a file i am accessing page.py which is located in /var/www/cgi-bin. I need this page to link to a css file which currently has the pathname /var/www/styles.css. Now I know I could link as: <link rel="stylesheet" href="**../styles.css**" type="text/css"> and the problem is solved but I would rather have a 'global' link, that I can use in other py files elsewhere in my filesystem and they will all point to /var/www/styles.css The information I have searched suggests that <link rel="stylesheet" href="**/var/www/styles.css**" type="text/css"> should work fine... but it doesn't. I have tried multiple combinations of everything I know but it doesn't seem to link as I would expect. Can anyone point me in the right direction?

  • Take data from an XML file and put it into a MySQL database

    - by Aidan
    Hi Guys, I'm looking to construct a script that would go through an XML file. Would find specific tags in it, put them in a table and fill the table with specific tags within them. I'm using MySQL 5.1 so loadXML isn't an option and I think that ExtractData() method wont be much use either.. but I don't really know. What would be the best way to go about this?

  • Partially flattening a list

    - by alj
    This is probably a really silly question but, given the example code at the bottom, how would I get a single list that retain the tuples? (I've looked at the itertools but it flattens everything) What I currently get is: ('id', 20, 'integer') ('companyname', 50, 'text') [('focus', 30, 'text'), ('fiesta', 30, 'text'), ('mondeo', 30, 'text'), ('puma', 30, 'text')] ('contact', 50, 'text') ('email', 50, 'text') what I would like is a single level list like: ('id', 20, 'integer') ('companyname', 50, 'text') ('focus', 30, 'text') ('fiesta', 30, 'text') ('mondeo', 30, 'text') ('puma', 30, 'text') ('contact', 50, 'text') ('email', 50, 'text') def getproducts(): temp_list=[] product_list=['focus','fiesta','mondeo','puma'] #usually this would come from a db for p in product_list: temp_list.append((p,30,'text')) return temp_list def createlist(): column_title_list = ( ("id",20,"integer"), ("companyname",50,"text"), getproducts(), ("contact",50,"text"), ("email",50,"text"), ) return column_title_list for item in createlist(): print item Thanks ALJ

  • UnicodeDecodeError from a GET-parameter in webapp2

    - by Aneon
    I'm getting a UnicodeDecodeError when recieving a GET-parameter from webapp2 that contains unicode characters, and then using it to do a NDB query. I get the same error message when manually running a unicode() on the parameter in the handler, so there either seems to be a problem in webapp2's URL routing or I've missed something. Preferably, all GET-parameters should be converted to unicode before getting passed into the handler so I don't need to do manual conversions in all of my handlers. I actually think it's worked before in an earlier version. The full error message read: UnicodeDecodeError: 'ascii' codec can't decode byte 0xc3 in position 1: ordinal not in range(128) The GET-parameter contains the following string: göteborg. It looks fine when I raise an Exception on it, but gives me an error when I (or NDB) use unicode() on it. EDIT: In NDB, it fails on the following code: File "C:\Program Files (x86)\Google\google_appengine\google\appengine\api\datastore_types.py", line 1562, in PackString pbvalue.set_stringvalue(unicode(value).encode('utf-8')) Thanks.

  • Setting `axes.linewidth` without changing the `rcParams` global dict

    - by mlvljr
    So, it seems one cannot do the following (it raises an error, since axes does not have a set_linewidth method): axes_style = {'linewidth':5} axes_rect = [0.1, 0.1, 0.9, 0.9] axes(axes_rect, **axes_style) and has to use the following old trick instead: rcParams['axes.linewidth'] = 5 # set the value globally ... # some code rcdefaults() # restore [global] defaults Is there an easy / clean way (may be one can set x- and y- axes parameters individually, etc)? P.S. If no, why?

  • How detect length of a numpy array with only one element?

    - by mishaF
    I am reading in a file using numpy.genfromtxt which brings in columns of both strings and numeric values. One thing I need to do is detect the length of the input. This is all fine provided there are more than one value read into each array. But...if there is only one element in the resulting array, the logic fails. I can recreate an example here: import numpy as np a = np.array(2.3) len(a) returns an error saying: TypeError: len() of unsized object however, If a has 2 or more elements, len() behaves as one would expect. import numpy as np a = np.array([2.3,3.6]) len(a) returns 2 My concern here is, if I use some strange exception handling, I can't distinguish between a being empty and a having length = 1.

  • What is good practice for writing web applications that control daemons (and their config files)

    - by Jones R
    Can someone suggest some basic advice on dealing with web applications that interact with configuration files like httpd.conf, bind zone files, etc. I understand that it's bad practice, in fact very dangerous to allow arbitrary execution of code without fully validating it and so on. But say you are tasked to write a small app that allows one to add vhosts to an apache configuration. Do you have your code execute with full privileges, do you write future variables into a database and have a cron job (with full privileges) execute a script that pulls the vars from the database and throws them into a template config file, etc. Some thoughts & contributions on this issue would be appreciated. tl;dr - how can you securely write a web app to update/create entries in a config file like apache's httpd.conf, etc.

  • Converting time period strings to value/unit pair

    - by randomtoor
    I need to parse the contents of a string that represents a time period. The format of the string is value/unit, e.g.: 1s, 60min, 24h. I would separate the actual value (an int) and unit (a str) to separated variables. At the moment I do it like this: def validate_time(time): binsize = time.strip() unit = re.sub('[0-9]','',binsize) if unit not in ['s','m','min','h','l']: print "Error: unit {0} is not valid".format(unit) sys.exit(2) tmp = re.sub('[^0-9]','',binsize) try: value = int(tmp) except ValueError: print "Error: {0} is not valid".format(time) sys.exit(2) return value,unit However, it is not ideal as things like 1m0 are also (wrongly) validated (value=10,unit=m). What is the best way to validate/parse this input?

    - by gpjones
    If I have two tables, Company and Sales, and I want to display both sets of data in a single list, how would I do this on Google App Engine using GQL?

  • Indexing one-dimensional numpy.array as matrix

    - by Alain
    I am trying to index a numpy.array with varying dimensions during runtime. To retrieve e.g. the first row of a n*m array a, you can simply do a[0,:] However, in case a happens to be a 1xn vector, this code above returns an index error: IndexError: too many indices As the code needs to be executed as efficiently as possible I don't want to introduce an if statement. Does anybody have a convenient solution that ideally doesn't involve changing any data structure types?
