• Automate paster create -t plone3_buildout

  - by roopesh

  I want to automate the process of plone3_buildout. Explanation: The default(the one I use) way of building a plone site is using paster, like so: paster create -t plone3_buildout This asks me a few questions and then create a default buildout for the site. What I want: I want to automate this process using buildout. My buildout will execute this paster command, feed in my preconfigured values to the paster. I haven't found a recipe which can do this. If someone has an idea of how to do this, please share the info. If there is a recipe which can feed values to interactive commands(with known output, like with plone3_buildout command), that would be useful too.

• Regex for Matching First Alphanumeric Character skipping (The |An? )

  - by TheLizardKing

  I have a list of artists, albums and tracks that I want to sort using the first letter of their respective name. The issue arrives when I want to ignore "The ", "A ", "An " and other various non-alphanumeric characters (Talking to you "Weird Al" Yankovic and [dialog]). Django has a nice start '^(An?|The) +' but I want to ignore those and a few others of my choice. I am doing this in Django, using a MySQL db with utf8_bin collation.

• How to use thread in Django

  - by zomboid

  I want to check users' subscribed dates for certain period. And send mail to users whose subscription is finishing (ex. reminds two days). I think the best way is using thread and timer to check dates. But I have no idea how to call this function. I don't want to make a separate program or shell. I want to combine this procedure to my django code. I tried to call this function in my settings.py file. But it seems it is not a good idea. It calls the fucntion and creates thread everytime i imported settings.

• Not able to pass multiple override parameters using nose-testconfig 0.6 plugin in nosetests

  - by Jaikit

  Hi, I am able to override multiple config parameters using nose-testconfig plugin only if i pass the overriding parameters on commandline. e.g. nosetests -c nose.cfg -s --tc=jack.env1:asl --tc=server2.env2:abc But when I define the same thing inside nose.cfg, than only the value for last parameter is modified. e.g. tc = server2.env2:abc tc = jack.env1:asl I checked the plugin code. It looks fine to me. I am pasting the part of plugin code below: parser.add_option( "--tc", action="append", dest="overrides", default = [], help="Option:Value specific overrides.") configure: if options.overrides: self.overrides = [] overrides = tolist(options.overrides) for override in overrides: keys, val = override.split(":") if options.exact: config[keys] = val else: ns = ''.join(['["%s"]' % i for i in keys.split(".") ]) # BUG: Breaks if the config value you're overriding is not # defined in the configuration file already. TBD exec('config%s = "%s"' % (ns, val)) Let me know if any one has any clue.

• Multi-part template issue with Jinja2

  - by Alan Harris-Reid

  Hi, When creating templates I typically have 3 separate parts (header, body, footer) which I combine to pass a singe string to the web-server (CherryPy in this case). My first approach is as follows... from jinja2 import Environment, FileSystemLoader env = Environment(loader=FileSystemLoader('')) tmpl = env.get_template('Body.html') page_body = tmpl.render() tmpl = env.get_template('Header.html') page_header = tmpl.render() tmpl = env.get_template('Footer.html') page_footer = tmpl.render() page_code = page_header + page_body + page_footer but this contains repetitious code, so my next approach is... def render_template(html_file): from jinja2 import Environment, FileSystemLoader env = Environment(loader=FileSystemLoader('')) tmpl = env.get_template(html_file) return tmpl.render() page_header = render_template('Header.html') page_body = render_template('Body.html') page_footer = render_template('Footer.html) However, this means that each part is created in its own environment - can that be a problem? Are there any other downsides to this approach? I have chosen the 3-part approach over the child-template approach because I think it may be more flexible (and easier to follow), but I might be wrong. Anyone like to convince me that using header, body and footer blocks might be better? Any advice would be appreciated. Alan

• How to create a backup from SqlAlchemy?

  - by swilliams

  I'm writing a Pylons app, and am trying to create a simple backup system where every table is serialized and tarred up into a single file for an administrator to download, and use to restore the app should something bad happen. I can serialize my table data just fine using the SqlAlchemy serializer, and I can deserialize it fine as well, but I can't figure out how to commit those changes back to the database. In order to serialize my data I am doing this: from myproject.model.meta import Session from sqlalchemy.ext.serializer import loads, dumps q = Session.query(MyTable) serialized_data = dumps(q.all()) In order to test things out, I go ahead and truncation MyTable, and then attempt to restore using serialized_data: from myproject.model import meta restore_q = loads(serialized_data, meta.metadata, Session) This doesn't seem to do anything... I've tried calling a Session.commit after the fact, individually walking through all the objects in restore_q and adding them, but nothing seems to work. What am I missing? Or is there a better way to do what I'm aiming for? I don't want to shell out and directly touch the database, since SqlAlchemy supports different database engines.

• How do I create a M2Crypto DSA object given parameters and key values?

  - by casey

  Using M2Crypto I'd like to create a DSA_pub object for verifying a DSA signature. I know q, p, g, and the public key, but the only way I know to instantiate a DSA object is using: dsa = DSA.set_params(q,p,g) dsa.gen_key() How do I assign the known public key?

• Storing a list of objects in GAE

  - by Dominic Bou-Samra

  I need to store some data that looks a little like this: xyz 123 abc 456 hij 678 rer 838 Now I would just store it as a traditional string and integer model, and put in the datastore. But the data changes regularly, and is ONLY relevant when looked at as a COLLECTION. So it needs to be store as either a list of lists, or a list of objects, both of which can't really be done without pickling as far as I know. Can anyone help? Even storing it as a text file may work :S

• Can DBRefs contain additional fields?

  - by Soviut

  I've encountered several situations when using MongoDB that require the use of DBRefs. However, I'd also like to cache some fields from the referenced document in the DBRef itself. {$ref:'user', $id:'10285102912A', username:'Soviut'} For example, I may want to have the username available even though the user document is referenced. This would provide me all the benefits of a single document approach; Faster querying and eliminating the need to do manual dereferencing in my code. While at the same time allowing me to use references where they make sense. The idea being that when the referenced document is updated (a user changes their name, for example) my business layer can automatically update all the documents that reference it. Ultimately, I'm wondering if it's considered good form to store additional fields on my DBRefs? Will it break anything? Will I lose my data each time a reference is rewritten? Will drivers like pymongo support it?

• Problem with Replacing special characters in a string

  - by Hossein

  Hi, I am trying to feed some text to a special pupose parser. The problem with this parser is that it is sensitive to ()[] characters and in my sentence in the text have quite a lot of these characters. The manual for the parser suggests that all the ()[] get replaced with \( \) \[ \]. So using str.replace i am using to attach \ to all of those charcaters. I use the code below: a = 'abcdef(1234)' a.replace('(','\(') however i get this as my output: 'abcdef\\(1234)' What is wrong with my code? can anyone provide me a solution to solve this for these characters?

• How to manually create a DBRef using pymongo?

  - by Soviut

  I want to create a DBRef manually so that I can add an additional field to it. However, when I try to pass the following: {'$ref': 'projects', '$id': '1029412409721', 'project_name': 'My Project'} Pymongo raises an error: pymongo.errors.InvalidName: key '$id' must not start with '$' It would seem that pymongo reserve the $ for the special key, leading me to wonder if it is even possible to do what I'm trying to do?

• Spaceship objects

  - by Jam

  I'm trying to make a program which creates a spaceship and I'm using the status() method to display the ship's name and fuel values. However, it doesn't seem to be working. I think I may have messed something up with the status() method. I'm also trying to make it so that I can change the fuel values, but I don't want to create a new method to do so. I think I've taken a horrible wrong turn somewhere in there. Help please! class Ship(object): def __init__(self, name="Enterprise", fuel=0): self.name=name self.fuel=fuel print "The spaceship", name, "has arrived!" def status(): print "Name: ", self.name print "Fuel level: ", self.fuel status=staticmethod(status) def main(): ship1=Ship(raw_input("What would you like to name this ship?")) fuel_level=raw_input("How much fuel does this ship have?") if fuel_level<0: self.fuel=0 else: self.fuel(fuel_level) ship2=Ship(raw_input("What would you like to name this ship?")) fuel_level2=raw_input("How much fuel does this ship have?") if fuel_level2<0: self.fuel=0 else: self.fuel(fuel_level2) ship3=Ship(raw_input("What would you like to name this ship?")) fuel_level3=raw_input("How much fuel does this ship have?") if fuel_level3<0: self.fuel=0 else: self.fuel(fuel_level3) Ship.status() main() raw_input("Press enter to exit.")

• Can this be done with the ORM? - Django

  - by RadiantHex

  Hi folks, I have a few item listed in a database, ordered through Reddit's algorithm. This is it: def reddit_ranking(post): t = time.mktime(post.created_on.timetuple()) - 1134000000 x = post.score if x>0: y=1 elif x==0: y=-0 else: y=-1 if x<0: z=1 else: z=x return (log(z) + y * t/45000) I'm wondering if there is any clever way of using Django's ORM, in order to UPDATE the models in bulk. Without doing this: items = Item.objects.filter(created_on__gte=datetime.now()-timedelta(days=7)) for item in items: item.reddit_rank = reddit_rank(item) item.save() I know about the F() object, but I can't figure out if this function can be performed inside the ORM. Any ideas? Help would be very much appreciated!

• Facebook Connect via Javascript doesn't close and doesn't pass session id

  I'm trying to authenticate users via Facebook Connect using a custom Javascript button: <form> <input type="button" value="Connect with Facebook" onclick="window.open('http://www.facebook.com/login.php?api_key=XXXXX&extern=1&fbconnect=1&req_perms=publish_stream,email&return_session=0&v=1.0&next=http%3A%2F%2Fwww.example.com%2Fxd_receiver.htm&fb_connect=1&cancel_url=http%3A%2F%2Fwww.example.com%2Fregister%2Fcancel', '_blank', 'top=442,width=480,height=460,resizable=yes', true)" onlogin='window.location="/register/step2"' /> </form> I am able to authenticate users. However after authentication, the popup window just stays open and the main window is not directed anywhere. In fact, it is the popup window that goes to "/register/step2" How can I get the login window to close as expected, and to pass the facebook session id to /register/step2? Thanks!

• Allowing users to delete their own comments in Django

  I am using the delete() function from django.contrib.comments.views.moderation module. The staff-member is allowed to delete ANY comment posts, which is completely fine. However, I would also like to give registered non-staff members the privilege to delete their OWN comment posts, and their OWN only. How can I accomplish this?
