  • Many to many self join through junction table

    - by Peter
    I have an EF model that can self-reference through an intermediary class to define a parent/child relationship. I know how to do a pure many-to-many relationship using the Map command, but for some reason going through this intermediary class is causing problems with my mappings. The intermediary class provides additional properties for the relationship. See the classes, modelBinder logic and error below: public class Equipment { [Key] public int EquipmentId { get; set; } public virtual List<ChildRecord> Parents { get; set; } public virtual List<ChildRecord> Children { get; set; } } public class ChildRecord { [Key] public int ChildId { get; set; } [Required] public int Quantity { get; set; } [Required] public Equipment Parent { get; set; } [Required] public Equipment Child { get; set; } } I've tried building the mappings in both directions, though I only keep one set in at a time: modelBuilder.Entity<ChildRecord>() .HasRequired(x => x.Parent) .WithMany(x => x.Children ) .WillCascadeOnDelete(false); modelBuilder.Entity<ChildRecord>() .HasRequired(x => x.Child) .WithMany(x => x.Parents) .WillCascadeOnDelete(false); OR modelBuilder.Entity<Equipment>() .HasMany(x => x.Parents) .WithRequired(x => x.Child) .WillCascadeOnDelete(false); modelBuilder.Entity<Equipment>() .HasMany(x => x.Children) .WithRequired(x => x.Parent) .WillCascadeOnDelete(false); Regardless of which set I use, I get the error: The foreign key component 'Child' is not a declared property on type 'ChildRecord'. Verify that it has not been explicitly excluded from the model and that it is a valid primitive property. when I try do deploy my ef model to the database. If I build it without the modelBinder logic in place then I get two ID columns for Child and two ID columns for Parent in my ChildRecord table. This makes sense since it tries to auto create the navigation properties from Equipment and doesn't know that there are already properties in ChildRecord to fulfill this need. I tried using Data Annotations on the class, and no modelBuilder code, this failed with the same error as above: [Required] [ForeignKey("EquipmentId")] public Equipment Parent { get; set; } [Required] [ForeignKey("EquipmentId")] public Equipment Child { get; set; } AND [InverseProperty("Child")] public virtual List<ChildRecord> Parents { get; set; } [InverseProperty("Parent")] public virtual List<ChildRecord> Children { get; set; } I've looked at various other answers around the internet/SO, and the common difference seems to be that I am self joining where as all the answers I can find are for two different types.

  • Python PyQt Timer Firmata

  • Multiple CodeSnippet in an XML .snippet file

    - by Frinavale
    I'm attempting to supplement the help features for my code by providing other developers with code snippets. These produce skeletons of code which demonstrate how to use/call my classes or methods. I've created a .snippet file and have placed it in the "%Visual Studio Folder%\Code Snippets\Visual Basic\My Snippets" folder. I've used the Code Snippets Manager and ensured that it included this folder so that I can access the snippets. Everything works well when I have 1 CodeSnippet tag within the root CodeSnippets tag.... When I add more than one CodeSnippet tag to the file (each with their own title, and their own code example) I'm experiencing something strange. The first CodeSnippet I've added contains code for adding something to my system, the second contains code for editing something in my system, and the third deleting something from the system. When I use the code snippet by right clicking and selecting "Insert Code Snippet", only the first code snippet in the file shows up as an option. When I select it, the code in the first CodeSnippet is inserted....but so is the code within the other CodeSnippet tags. Do you have to have a separate XML .snippet file for each code snippet you want to make available? After reading through MSDN about creating Code Snippets I was under the impression that this could all be done within one file. It seems that I'm not understanding something very basic here and would love to find the answer but apparently Code Snippets are under used so finding the answer has proven to be a little trickier than I first thought it would be. Thanks, -Frinny

  • python: how to design a container with elements that must reference their container

    - by Luke404
    (the title is admittedly not that great. Please forgive my English, this is the best I could think of) I'm writing a python script that will manage email domains and their accounts, and I'm also a newby at OOP design. My two (related?) issues are: the Domain class must do special work to add and remove accounts, like adding/removing them to the underlying implementation how to manage operations on accounts that must go through their container To solve the former issue I'd add a factory method to the Domain class that'll build an Account instance in that domain, and a 'remove' (anti-factory?) method to handle deletions. For the latter this seems to me "anti-oop" since what would logically be an operation on an Account (eg, change password) must always reference the containing Domain. Seems to me that I must add to the Account a reference back to the Domain and use that to get data (like the domain name) or call methods on the Domain class. Code example (element uses data from the container) that manages an underlying Vpopmail system: class Account: def __init__(self, name, password, domain): self.name = name self.password = password self.domain = domain def set_password(self, password): os.system('vpasswd %s@%s %s' % (self.name, self.domain.name, password) self.password = password class Domain: def __init__(self, domain_name): self.name = domain_name self.accounts = {} def create_account(self, name, password): os.system('vadduser %s@%s %s' % (name, self.name, password)) account = Account(name, password, self) self.accounts[name] = account def delete_account(self, name): os.system('vdeluser %s@%s' % (name, self.name)) del self.accounts[name] another option would be for Account.set_password to call a Domain method that would do the actual work - sounds equally ugly to me. Also note the duplication of data (account name also as dict key), it sounds logical (account names are "primary key" inside a domain) but accounts need to know their own name.

  • Django tests failing on invalid keyword argument

    - by Darwin Tech
    I have a models.py like so: from django.db import models from django.contrib.auth.models import User from datetime import datetime class UserProfile(models.Model): user = models.OneToOneField(User) def __unicode__(self): return self.user.username class Project(models.Model): user = models.ForeignKey(UserProfile) created = models.DateTimeField(auto_now_add=True) updated = models.DateTimeField(auto_now=True) product = models.ForeignKey('tool.product') module = models.ForeignKey('tool.module') model = models.ForeignKey('tool.model') zipcode = models.IntegerField(max_length=5) def __unicode__(self): return unicode(self.id) And my tests.py: from django.test import TestCase, Client # --- import app models from django.contrib.auth.models import User from tool.models import Module, Model, Product from user_profile.models import Project, UserProfile # --- unit tests --- # class UserProjectTests(TestCase): fixtures = ['admin_user.json'] def setUp(self): self.product1 = Product.objects.create( name='bar', ) self.module1 = Module.objects.create( name='foo', enable=True ) self.model1 = Model.objects.create( module=self.module1, name='baz', enable=True ) self.user1 = User.objects.get(pk=1) ... def test_can_create_project(self): self.project1 = Model.objects.create( user=self.user1, product=self.product1, module=self.module1, model=self.model1, zipcode=90210 ) self.assertEquals(self.project1.zipcode, 90210) But I get a TypeError: 'product' is an invalid keyword argument for this function error. I'm not sure what is failing but I'm guessing something to do with the FK relationships... Any help would be much appreciated.

  • Django: how to cleanup form fields and avoid code duplication

    - by Alexander Konstantinov
    Quite often I need to filter some form data before using it (saving to database etc.) Let's say I want to strip whitespaces and replace repeating whitespaces with a single one in most of the text fields, in many forms. It's not difficult to do this using clean_<fieldname> methods: # Simplified model with two text fields class MyModel(models.Model): title = models.CharField() description = models.CharField() # Model-based form class MyForm(forms.ModelForm): class Meta: model = MyModel def clean_title(self): title = self.cleaned_data['title'] return re.sub(r'\s{2,}', ' ', title.strip()) def clean_description(self): description = self.cleaned_data['description'] return re.sub(r'\s{2,}', ' ', description.strip()) It does exactly what I need, and has a nice side effect which I like: if user enters only whitespaces, the field will be considered empty and therefore invalid (if it is required) and I don't even have to throw a ValidationError. The obvious problem here is code duplication. Even if I'll create some function for that, say my_text_filter, I'll have to call it for every text field in all my forms: from myproject.filters import my_text_filter class MyForm(forms.ModelForm): class Meta: model = MyModel def clean_title(self): return my_text_filter(self.cleaned_data['title']) def clean_description(self): return my_text_filter(self.cleaned_data['description']) The question: is there any standard and simple way in Django (I use version 1.2 if that matters) to do this (like, for example, by adding property validators = {'title': my_text_filter, 'description': my_text_filter} to MyModel), or at least some more or less standard workaround? I've read about form validation and validators in the documentation, but couldn't find what I need there.

  • python can't start a new thread

    - by Giorgos Komnino
    I am building a multi threading application. I have setup a threadPool. [ A Queue of size N and N Workers that get data from the queue] When all tasks are done I use tasks.join() where tasks is the queue . The application seems to run smoothly until suddently at some point (after 20 minutes in example) it terminates with the error thread.error: can't start new thread Any ideas? Edit: The threads are daemon Threads and the code is like: while True: t0 = time.time() keyword_statuses = DBSession.query(KeywordStatus).filter(KeywordStatus.status==0).options(joinedload(KeywordStatus.keyword)).with_lockmode("update").limit(100) if keyword_statuses.count() == 0: DBSession.commit() break for kw_status in keyword_statuses: kw_status.status = 1 DBSession.commit() t0 = time.time() w = SWorker(threads_no=32, network_server='http://192.168.1.242:8180/', keywords=keyword_statuses, cities=cities, saver=MySqlRawSave(DBSession), loglevel='debug') w.work() print 'finished' When the daemon threads are killed? When the application finishes or when the work() finishes? Look at the thread pool and the worker (it's from a recipe ) from Queue import Queue from threading import Thread, Event, current_thread import time event = Event() class Worker(Thread): """Thread executing tasks from a given tasks queue""" def __init__(self, tasks): Thread.__init__(self) self.tasks = tasks self.daemon = True self.start() def run(self): '''Start processing tasks from the queue''' while True: event.wait() #time.sleep(0.1) try: func, args, callback = self.tasks.get() except Exception, e: print str(e) return else: if callback is None: func(args) else: callback(func(args)) self.tasks.task_done() class ThreadPool: """Pool of threads consuming tasks from a queue""" def __init__(self, num_threads): self.tasks = Queue(num_threads) for _ in range(num_threads): Worker(self.tasks) def add_task(self, func, args=None, callback=None): ''''Add a task to the queue''' self.tasks.put((func, args, callback)) def wait_completion(self): '''Wait for completion of all the tasks in the queue''' self.tasks.join() def broadcast_block_event(self): '''blocks running threads''' event.clear() def broadcast_unblock_event(self): '''unblocks running threads''' event.set() def get_event(self): '''returns the event object''' return event

  • python gui events out of order

    - by dave
    from Tkinter import * from tkMessageBox import * class Gui: def __init__(self, root): self.container = Frame(root) self.container.grid() self.inputText = Text(self.container, width=50, height=8) self.outputText = Text(self.container, width=50, height=8, bg='#E0E0E0', state=DISABLED) self.inputText.grid(row=0, column=0) self.outputText.grid(row=0, column=1) self.inputText.bind("<Key>", self.translate) def translate(self, event): input = self.inputText.get(0.0, END) output = self.outputText.get(0.0, END) self.outputText.config(state=NORMAL) self.outputText.delete(0.0, END) self.outputText.insert(INSERT, input) self.outputText.config(state=DISABLED) showinfo(message="Input: %s characters\nOutput: %s characters" % (len(input), len(input))) root = Tk() #toplevel object app = Gui(root) #call to the class where gui is defined root.mainloop() #enter event loop Working on a gui in tkinter I'm a little confused as to the sequence the event handlers are run. If you run the above code you'll hopefully see... 1) Editing the text widget triggers the event handler but it seems to fire it off without registering the actual change, 2) Even when the text widget is cleared (ie, keep pressing BackSpace) it still seems to have a one character length string, 3) The output widget only receives its update when the NEXT event trigger is fired despite the fact the data came on the previous event. Is this just how bindings work in tkinter or am i missing something here? The behaviour i would like when updating the input widget is: 1) Show the change, 2) Enter event handler, 3) Update output widget, 4) Show message box.

  • I don't like Python functions that take two or more iterables. Is it a good idea?

    - by Xavier Ho
    This question came from looking at this question on Stackoverflow. def fringe8((px, py), (x1, y1, x2, y2)): Personally, it's been one of my pet peeves to see a function that takes two arguments with fixed-number iterables (like a tuple) or two or more dictionaries (Like in the Shotgun API). It's just hard to use, because of all the verbosity and double-bracketed enclosures. Wouldn't this be better: >>> class Point(object): ... def __init__(self, x, y): ... self.x = x ... self.y = y ... >>> class Rect(object): ... def __init__(self, x1, y1, x2, y2): ... self.x1 = x1 ... self.y1 = y1 ... self.x2 = x2 ... self.y2 = y2 ... >>> def fringe8(point, rect): ... # ... ... >>> >>> point = Point(2, 2) >>> rect = Rect(1, 1, 3, 3) >>> >>> fringe8(point, rect) Is there a situation where taking two or more iterable arguments is justified? Obviously the standard itertools Python library needs that, but I can't see it being pretty in maintainable, flexible code design.

  • PGU HTML Renderer can't render most sites

    - by None
    I am trying to make a web browser using pygame. I am using PGU for html rendering. It works fine when I visit simple sites, like example.com, but when I try and load anything more complex that uses an html form, like google, I get this error: UnboundLocalError: local variable 'e' referenced before assignment I looked in the PGU html rendering file and found this code segment: def start_input(self,attrs): r = self.attrs_to_map(attrs) params = self.map_to_params(r) #why bother #params = {} type_,name,value = r.get('type','text'),r.get('name',None),r.get('value',None) f = self.form if type_ == 'text': e = gui.Input(**params) self.map_to_connects(e,r) self.item.add(e) elif type_ == 'radio': if name not in f.groups: f.groups[name] = gui.Group(name=name) g = f.groups[name] del params['name'] e = gui.Radio(group=g,**params) self.map_to_connects(e,r) self.item.add(e) if 'checked' in r: g.value = value elif type_ == 'checkbox': if name not in f.groups: f.groups[name] = gui.Group(name=name) g = f.groups[name] del params['name'] e = gui.Checkbox(group=g,**params) self.map_to_connects(e,r) self.item.add(e) if 'checked' in r: g.value = value elif type_ == 'button': e = gui.Button(**params) self.map_to_connects(e,r) self.item.add(e) elif type_ == 'submit': e = gui.Button(**params) self.map_to_connects(e,r) self.item.add(e) elif type_ == 'file': e = gui.Input(**params) self.map_to_connects(e,r) self.item.add(e) b = gui.Button(value='Browse...') self.item.add(b) def _browse(value): d = gui.FileDialog(); d.connect(gui.CHANGE,gui.action_setvalue,(d,e)) d.open(); b.connect(gui.CLICK,_browse,None) self._locals[r.get('id',None)] = e I got the error in the last line, because e wasn't defined. I am guessing the reason for this is that the if statement that checks the type of the input and creates the e variable didn't match anything. I added a line to print the _type variable and I got 'hidden' when i tried google and apple. Is there any way to render form items that have the type 'hidden' with PGU?

  • On-Demand Python Thread Start/Join Freezing Up from wxPython GUI

    - by HokieTux
    I'm attempting to build a very simple wxPython GUI that monitors and displays external data. There is a button that turns the monitoring on/off. When monitoring is turned on, the GUI updates a couple of wx StaticLabels with real-time data. When monitoring is turned off, the GUI idles. The way I tried to build it was with a fairly simple Python Thread layout. When the 'Start Monitoring' button is clicked, the program spawns a thread that updates the labels with real-time information. When the 'Stop Monitoring' button is clicked, thread.join() is called, and it should stop. The start function works and the real-time data updating works great, but when I click 'Stop', the whole program freezes. I'm running this on Windows 7 64-bit, so I get the usual "This Program has Stopped Responding" Windows dialog. Here is the relevant code: class MonGUI(wx.Panel): def __init__(self, parent): wx.Panel.__init__(self, parent) ... ... other code for the GUI here ... ... # Create the thread that will update the VFO information self.monThread = Thread(None, target=self.monThreadWork) self.monThread.daemon = True self.runThread = False def monThreadWork(self): while self.runThread: ... ... Update the StaticLabels with info ... (This part working) ... # Turn monitoring on/off when the button is pressed. def OnClick(self, event): if self.isMonitoring: self.button.SetLabel("Start Monitoring") self.isMonitoring = False self.runThread = False self.monThread.join() else: self.button.SetLabel("Stop Monitoring") self.isMonitoring = True # Start the monitor thread! self.runThread = True self.monThread.start() I'm sure there is a better way to do this, but I'm fairly new to GUI programming and Python threads, and this was the first thing I came up with. So, why does clicking the button to stop the thread make the whole thing freeze up?

  • How to generate a client certificate using a third party CA-NOT Self Signed CA

    - by Bryan
    I am trying to trying to export a client certificate for use with a web browser. The goal is to restrict access using the <Location directive to the admin area. I have seen numerous tutorials on using self signed CAs. How would you do this using a third party? 1) Do I need to include the CA in the client pfx if it is a trusted root CA? I have seen both examples. Without CA: openssl pkcs12 -export -inkey KEYFILENAME -in CERTFILEFILENAME -out XXX.pfx With CA: openssl pkcs12 -export -in my.crt- inkey my.key -certfile my.bundle -out my.pfx 2) Do I need to still include SSLCACertificateFile for trusted CA in the httpd.conf setup? SSLVerifyClient none SSLCACertificateFile conf/ssl.crt/ca.crt <Location /secure/area> SSLVerifyClient require SSLVerifyDepth 1 </Location> http://www.modssl.org/docs/2.8/ssl_howto.html#ToC8

  • J: Self-reference in bubble sort tacit implementation

    - by Yasir Arsanukaev
    Hello people! Since I'm beginner in J I've decided to solve a simple task using this language, in particular implementing the bubblesort algorithm. I know it's not idiomatically to solve such kind of problem in functional languages, because it's naturally solved using array element transposition in imperative languages like C, rather than constructing modified list in declarative languages. However this is the code I've written: (((<./@(2&{.)), $:@((>./@(2&{.)),2&}.)) ^: (1<#)) ^: # Let's apply it to an array: (((<./@(2&{.)), $:@((>./@(2&{.)),2&}.)) ^: (1<#)) ^: # 5 3 8 7 2 2 3 5 7 8 The thing that confuses me is $: referring to the statement within the outermost parentheses. Help says that: $: denotes the longest verb that contains it. The other book (~ 300 KiB) says: 3+4 7 5*20 100 Symbols like + and * for plus and times in the above phrases are called verbs and represent functions. You may have more than one verb in a J phrase, in which case it is constructed like a sentence in simple English by reading from left to right, that is 4+6%2 means 4 added to whatever follows, namely 6 divided by 2. Let's rewrite my code snippet omitting outermost ()s: ((<./@(2&{.)), $:@((>./@(2&{.)),2&}.)) ^: (1<#) ^: # 5 3 8 7 2 2 3 5 7 8 Reuslts are the same. I couldn't explain myself why this works, why only ((<./@(2&{.)), $:@((>./@(2&{.)),2&}.)) ^: (1<#) is treated as the longest verb for $: but not the whole expression ((<./@(2&{.)), $:@((>./@(2&{.)),2&}.)) ^: (1<#) ^: # and not just (<./@(2&{.)), $:@((>./@(2&{.)),2&}.), because if ((<./@(2&{.)), $:@((>./@(2&{.)),2&}.)) ^: (1<#) is a verb, it should also form another verb after conjunction with #, i. e. one might treat the whole sentence (first snippet) as a verb. Probably there's some limit for the verb length limited by one conjunction. Look at the following code (from here): factorial =: (* factorial@<:) ^: (1&<) factorial 4 24 factorial within expression refers to the whole function, i. e. (* factorial@<:) ^: (1&<). Following this example I've used a function name instead of $:: bubblesort =: (((<./@(2&{.)), bubblesort@((>./@(2&{.)),2&}.)) ^: (1<#)) ^: # bubblesort 5 3 8 7 2 2 3 5 7 8 I expected bubblesort to refer to the whole function, but it doesn't seem true for me since the result is correct. Also I'd like to see other implementations if you have ones, even slightly refactored. Thanks.

  • Getting hierarchy data from a self-referencing table

    - by Emanuil
    Let's say you have the following table: items(item_id, item_parent) ... and it is a self-referencing table as item_parent refers to item_id. What SQL query would you use to SELECT all items in the table along with their depth where the depth of an item is the sum of all parents and grand parents of that item. If the following is the content of the table: item_id item_parent ----------- ----------- 1 0 2 0 3 2 4 2 5 3 ... the query should retrieve the following set of objects: {"item_id":1,"depth":0} {"item_id":2,"depth":0} {"item_id":3,"depth":1} {"item_id":4,"depth":1} {"item_id":5,"depth":2} P.S. I'm looking for a MySQL supported approach.

  • Drupal - no self-linking

    - by pygorex1
    So, I've added several pages to my Drupal install and linking to the pages using URL aliases via the Path module. So far so good - http://mydrupal/node/1 becomes http://mydrupal/about which is exactly what I'm looking for. Then I'm adding these links to the primary navigation and outputting the primary links via a custom theme (copy and paste the primary link code from the Chameleon theme). Here's the problem: when viewing http://mydrupal/about the page links to itself - that is the "About" link at http://mydrupal/about is still linking to http://mydrupal/about - the behavior I'm looking for is to have the "About" text display without a link. In summary: how do I prevent self-linking of pages when displaying the primary navigation?

  • Right way to create [self]respawning app in python

    - by grapescan
    I am using jabber bot written in python to log some MUC talks. Sometimes it drops on some network or XMPP problems. In this case I have to start it again by myself. The goal is to make it "self-respawning". I have some variants about how to do it. Bot is one process. Another process monitors its activity and starts it if bot died. Main process spawns bot subprocess and controls it. Also I think daemonizing bot process is useful here. Platform is Linux, as you could guess. What is the right way to solve this problem?

  • telling java to accept self-signed ssl certificate

    - by Nikita Rybak
    It looks like a standard question, but I couldn't find clear directions anywhere. I have java code trying to connect server with probably self-signed (or expired) certificate. It gives something like this [HttpMethodDirector] I/O exception (javax.net.ssl.SSLHandshakeException) caught when processing request: sun.security.validator.ValidatorException: PKIX path building failed: sun.security.provider.certpath.SunCertPathBuilderException: unable to find valid certification path to requested target As I understand, I have to play around with keytool and tell java that it's ok to allow this connection. But all comments I've found assume I'm fully proficient with keytool, like "generate private key for server and import it into keystore". And I'm not. Is there anybody who could post detailed instructions? I'm running unix, so bash script would be best. Not sure if it's important, but code executed in jboss. Thanks a lot!

    - by blog.blomqvist.no
    Aim: To have own OpenId provider connected with self-hosted Wordpress blog, so Wordpress admin could use his OpenId to login to Admin Panel, and also to comment other blogs with this OpenId. Blog address: http://blog.blomqvist.no OpenId provider: /id/ OpenId created: same as blog address WP Plugins used: WP-Yadis 1.2.1 XRDS-Simple 1.0 OpenId 3.3.2 I have installed phpMyId as OpenId provider.

However, i can't use this OpenId anywhere else, not on blogspot, not on other wordpress blogs etc.

  • Self-extracting Delphi program

    - by Steve
    I'm writing an updater program in Delphi7 which will be run once, but needs many files to run. What I'd like the achieve: 1, User runs exe 2, Exe unpacks files, runs updater 3, If updater detects and error, prompts the user to send log in e-mail 4, After the updater is run, temporary files are deleted (some of these files are dlls used by the updater program, so the updater has to be closed before the files can be deleted) Can anyone recommend a good solution? I've thought about using Inno Setup (too complicated for such an easy task) or using a self-extracting zip file (but how to delete the files afterwards)? Thanks!

  • jQuery: Self Executing Plugin?

    - by GnrlBzik
    I am working on expansion of my jQuery plug-in authoring knowledge, just playing around with my own ideas for learning benefits. So i was wondering how you guys tackle the need of plugin executing without any user specific input. So I have a need for plug-in that executes right away after document is ready, without any user's specific input just as long as doc is loaded, so the only way I see how to execute plug-in on it's own is to attach handler to ready listener that executes my function which I extended the jQuery with. And because this needs to be self enclosed, part of the code, I attach handler to event listener within the function. So how else could one tackle this? Any take at this is appreciated. Thank you in advance everyone.
