  • SQL searching table fields with LIKE

    - by Tom Gullen
    Given your data stored somewhere in a database: Hello my name is Tom I like dinosaurs to talk about SQL. SQL is amazing. I really like SQL. We want to implement a site search, allowing visitors to enter terms and return relating records. A user might search for: Dinosaurs And the SQL: WHERE articleBody LIKE '%Dinosaurs%' Copes fine with returning the correct set of records. How would we cope however, if a user mispells dinosaurs? IE: Dinosores (Poor sore dino). How can we search allowing for error in spelling? We can associate common misspellings we see in search with the correct spelling, and then search on the original terms + corrected term, but this is time consuming to maintain. Any way programatically?

  • Django: many-to-one fields and data integrity

    - by John
    Let's say that I have a Person who runs an inventory system. Each Person has some Cars, and each Car has a very large number of Parts (thousands, let's say). A Person, Bob, uses a Django form to create a Car. Now, Bob goes to create some Parts. It is only at the form level that Django knows that the Parts belong to some specific Car, and that the Parts.ForeignKey(Car) field should only have a specific Car as a choice. When creating a Part, you have to mess with the form's constructor or similar in order to limit the choice of Cars to only the cars owned by Bob. It does not seem proper that to enforce this ownership at the form level. It seems that other users' Cars must be inaccessible to anyone but the owner of the Car. What do you all think about this, and is there any way to enforce this?

  • Creating a custom ribbon button in VS 2008 Standard

    - by Kevin L.
    I want to create a custom ribbon button within Outlook 2007 using Visual Studio 2008 Standard, but am unsure how to proceed. Most of the resources I've found mention VS 2008 Pro, and this SO answer mentions that VSTO is not even included in Standard. Is creating custom ribbon buttons possible using Visual Studio 2008 Standard? If so, where should I start?

  • Get CGI Fields from URL Python

    - by user299196
    When using the cgi module in Python, I can't seem to figure out how to extract CGI variables in the URL. For example if the url servercgi.py?name=user , how do I get 'name' after import cgi? For some reason, form.getvalue and form['user'] do not work but if I print the object, I see something like FieldStorage(None, None, [MiniFieldStoreage('name', 'user')]).

  • Why won't anyone accept public fields in C#?

    - by Dmitri Nesteruk
    Seems like every C# static analyzer wants to complain when it sees a public field. But why? Surely there are cases where a public (or internal) field is enough, and there is no point in having a property with its get_ and set_ methods? What if I know for sure that I won't be redefining the field or adding to it (side effects are bad, right?) - shouldn't a simple field suffice?

  • HTTP authentication logout via PHP

    What is the correct way to log out of HTTP authentication protected folder? There are workarounds that can achieve this, but they are potentially dangerous because they can be buggy or don't work in certain situations / browsers. That is why I am looking for correct and clean solution.

  • How do I force or add the content length for ajax type POST requests in Firefox?

    - by Jayson
    I'm trying to POST a http request using ajax, but getting a response from the apache server using modsec_audit that: "POST request must have a Content-Length header." I do not want to disable this in modsec_audit. This occurs only in firefox, and not IE. Further, I switched to using a POST rather than a GET to keep IE from caching my results. This is a simplified version of the code I'm using for the request, I'm not using any javascript framework. function getMyStuff(){ var SearchString = ''; /* build search string */ ... /* now do request */ var xhr = createXMLHttpRequest(); var RequestString = 'someserverscript.cfm' + SearchString; xhr.open("POST", RequestString, true); xhr.onreadystatechange = function(){ processResponse(xhr); } xhr.send(null); } function processResponse(xhr){ var serverResponse = xhr.responseText; var container = document.getElementById('myResultsContainer'); if (xhr.readyState == 4){ container.innerHTML = serverResponse; } } function createXMLHttpRequest(){ try { return new ActiveXObject("Msxml2.XMLHTTP"); } catch (e) {} try { return new ActiveXObject("Microsoft.XMLHTTP"); } catch (e) {} try { return new XMLHttpRequest(); } catch(e) {} return null; } How do I force or add the content length for ajax type POST requests in Firefox?

  • Django m2m form appearing fields

    - by dana
    I have a classroom application,and a follow relation. Users can follow each other and can create classrooms.When a user creates a classroom, he can invite only the people that are following him. The Classroom model is a m2m to User table. i have in models. py: class Classroom(models.Model): creator = models.ForeignKey(User) classname = models.CharField(max_length=140, unique = True) date = models.DateTimeField(auto_now=True) open_class = models.BooleanField(default=True) members = models.ManyToManyField(User,related_name="list of invited members") and in models.py of the follow application: class Relations(models.Model): initiated_by = models.ForeignKey(User, editable=False) date_initiated = models.DateTimeField(auto_now=True, editable = False) follow = models.ForeignKey(User, editable = False, related_name = "follow") date_follow = models.DateTimeField(auto_now=True, editable = False) and in views.py of the classroom app: def save_classroom(request, username): if request.method == 'POST': u = User.objects.get(username=username) form = ClassroomForm(request.POST, request.FILES) if form.is_valid(): new_obj = form.save(commit=False) new_obj.creator = request.user r = Relations.objects.filter(initiated_by = request.user) # new_obj.members = new_obj.save() return HttpResponseRedirect('.') else: form = ClassroomForm() return render_to_response('classroom/classroom_form.html', { 'form': form, }, context_instance=RequestContext(request)) i'm using a ModelForm for the classroom form, and the default view, taking in consideration my many to many relation with User table, in the field Members, is a list of all Users in my database. But i only want in that list the users that are in a follow relationship with the logged in user - the one who creates the classroom. How can i do that? Thanks!

  • C# inheritance of fields

    - by Emil D
    This is probably a silly question, but here it goes.Imagine you have the following classes: public class C { } public class D : C { //A subclass of C } public class A { C argument; } Now, I want to have a class B, that inherits from A.This class would obviously inherit the "argument" field, but I wish to force the "argument" field in B to be of type D, rather than C.Since D inherits from C this shouldn't create any problems. So, how would achieve this in c# ?

  • Validate form fields from InfoPath custom code

    - by Alex Angas
    I'm developing an InfoPath form for Forms Services. It has these views: View 1 asks the user to input some basic initial data View 2 calls a web service based on data in View 1 and populates drop-downs accordingly At the bottom of View 1 I've added a Next > button to move to View 2. As part of clicking that button I would like the inputs in View 1 to be validated first. However, there don't appear to be any rules that validate a view or anything in the object model to execute validation rules. Is there code that can trigger a field's validation event?

  • Does ADFS2.0 provide custom authentication stores?

    - by chugh97
    I wanted to find out if ADFS2.0 provides a way for users to be authenticated with a Custom Store? Version 1.0 you could only authenticate users in the Windows domain, using Forms/Windows Integrated/Cardspace. I have an ASP.NEt website, which I would like the users to be authenticated against a custom store in SQL and then ADFS2.0 to take care of the claims issued to the user...

  • Using MongoDB's map/reduce to "group by" two fields

    - by ibz
    I need something slightly more complex than the examples in the MongoDB docs and I can't seem to be able to wrap my head around it. Say I have a collection of objects of the form {date: "2010-10-10", type: "EVENT_TYPE_1", user_id: 123, ...} Now I want to get something similar to a SQL GROUP BY query, grouping over both date and type. That is, I want the number of events of each type in each day. Also, I'd like to make it unique by user_id, ie. if a user has more events in the same day, count it only once. I'm trying to do this with map/reduce. I do db.logs.mapReduce(function() { emit(this.type, 1); }, function(k, vals) { var total = 0; for (var i = 0; i < vals.length; i++) total += vals[i]; return total; }}) which nicely groups by type, but now, how can I group by date at the same time? Seems the key in emit() can't be an array (I thought about doing emit([this.date, this.type], 1)). Also, how can I ensure the per-user uniqueness? I'm just starting with MongoDB and I'm still having trouble grasping the basic concepts. Also, there is not much documentation available out there. Any help from more experienced users is appreciated. Thanks!
