  • how to populate an entity you have extended in the Entity Framework?

    - by user169867
    I have an entity in my EDMX that I've extended with a few fields in a partial class like this: public partial class Employee { public string JobName {get;set;} } These properties are for display only. In the above example say the entity has a JobTypeID property. I wish JobName to be populated w/ the name that belongs to that JobTypeID. Is there anyway to query the employee record in EF including the value for the JobName property w/o explicity assigning each field using select()? The reason I ask is that there are a lot of fields in the Employee entity so I'd like to be able to take advantage of something like: ctx.Employees.Where(e=>e.EmployeeID==employeeID).Single() ...add somehow fill in JobName too Is this possible?

  • Is it possible to use Sphinx search with dynamic conditions?

    - by Fedyashev Nikita
    In my web app I need to perform 3 types of searching on items table with the following conditions: items.is_public = 1 (use title field for indexing) - a lot of results can be retrieved(cardinality is much higher than in other cases) items.category_id = {X} (use title + private_notes fields for indexing) - usually less than 100 results items.user_id = {X} (use title + private_notes fields for indexing) - usually less than 100 results I can't find a way to make Sphinx work in all these cases, but it works well in 1st case. Should I use Sphinx just for the 1st case and use plain old "slow" FULLTEXT searching in MySQL(at least because of lower cardinality in 2-3 cases)? Or is it just me and Sphinx can do pretty much everything?

  • getting Cannot identify image file when trying to create thumbnail in django

    - by Mo J. Mughrabi
    Am trying to create a thumbnail in django, am trying to build a custom class specifically to be used for generating thumbnails. As following from StringIO import StringIO from PIL import Image class Thumbnail(object): source = '' size = (50, 50) output = '' def __init__(self): pass @staticmethod def load(src): self = Thumbnail() self.source = src return self def generate(self, size=(50, 50)): if not isinstance(size, tuple): raise Exception('Thumbnail class: The size parameter must be an instance of a tuple.') self.size = size # resize properties box = self.size factor = 1 fit = True image = Image.open(self.source) # Convert to RGB if necessary if image.mode not in ('L', 'RGB'): image = image.convert('RGB') while image.size[0]/factor > 2*box[0] and image.size[1]*2/factor > 2*box[1]: factor *=2 if factor > 1: image.thumbnail((image.size[0]/factor, image.size[1]/factor), Image.NEAREST) #calculate the cropping box and get the cropped part if fit: x1 = y1 = 0 x2, y2 = image.size wRatio = 1.0 * x2/box[0] hRatio = 1.0 * y2/box[1] if hRatio > wRatio: y1 = int(y2/2-box[1]*wRatio/2) y2 = int(y2/2+box[1]*wRatio/2) else: x1 = int(x2/2-box[0]*hRatio/2) x2 = int(x2/2+box[0]*hRatio/2) image = image.crop((x1,y1,x2,y2)) #Resize the image with best quality algorithm ANTI-ALIAS image.thumbnail(box, Image.ANTIALIAS) # save image to memory temp_handle = StringIO() image.save(temp_handle, 'png') temp_handle.seek(0) self.output = temp_handle return self def get_output(self): return self.output.read() the purpose of the class is so i can use it inside different locations to generate thumbnails on the fly. The class works perfectly, I've tested it directly under a view.. I've implemented the thumbnail class inside the save method of the forms to resize the original images on saving. in my design, I have two fields for thumbnails. I was able to generate one thumbnail, if I try to generate two it crashes and I've been stuck for hours not sure whats the problem. Here is my model class Image(models.Model): article = models.ForeignKey(Article) title = models.CharField(max_length=100, null=True, blank=True) src = models.ImageField(upload_to='publication/image/') r128 = models.ImageField(upload_to='publication/image/128/', blank=True, null=True) r200 = models.ImageField(upload_to='publication/image/200/', blank=True, null=True) uploaded_at = models.DateTimeField(auto_now=True) Here is my forms class ImageForm(models.ModelForm): """ """ class Meta: model = Image fields = ('src',) def save(self, commit=True): instance = super(ImageForm, self).save(commit=True) file = Thumbnail.load(instance.src) instance.r128 = SimpleUploadedFile( instance.src.name, file.generate((128, 128)).get_output(), content_type='image/png' ) instance.r200 = SimpleUploadedFile( instance.src.name, file.generate((200, 200)).get_output(), content_type='image/png' ) if commit: instance.save() return instance the strange part is, when i remove the line which contains instance.r200 in the form save. It works fine, and it does the thumbnail and stores it successfully. Once I add the second thumbnail it fails.. Any ideas what am doing wrong here? Thanks Update: I tried earlier doing the following but I still got the same error class ImageForm(models.ModelForm): """ """ class Meta: model = Image fields = ('src',) def save(self, commit=True): instance = super(ImageForm, self).save(commit=True) instance.r128 = SimpleUploadedFile( instance.src.name, Thumbnail.load(instance.src).generate((128, 128)).get_output(), content_type='image/png' ) instance.r200 = SimpleUploadedFile( instance.src.name, Thumbnail.load(instance.src).generate((200, 200)).get_output(), content_type='image/png' ) if commit: instance.save() return instance

  • How to add a sequence column to an existing table with records

    - by user1888543
    I had created a new table named USERLOG with two fields from a previous VIEW. The table already consist of about 9000 records. The two fields taken from the VIEW, i.e. weblog_views consist of IP (consists of IP address), and WEB_LINK (consists of URL). This is the code I used, CREATE TABLE USERLOG AS SELECT C_IP, WEB_LINK FROM weblog_views; I want to add another column to this table called the USER_ID, which would consists of a sequence starting with 1 to 9000 records to create a unique id for each existing rows. I need help with this part. I'm using Oracle SQL Developer: ODMiner version 3.0.04. I tried using the AUTO-INCREMENT option, ALTER TABLE USERLOG ADD USER_ID INT UNSIGNED NOT NULL AUTO_INCREMENT; But I get an error with this, Error report: SQL Error: ORA-01735: invalid ALTER TABLE option 01735. 00000 - "invalid ALTER TABLE option" So, I would really appreciate any help that I can get!

  • How can I retrieve the values of controls in the form that posted?

    - by Mike at KBS
    I know this has got to be the simplest-sounding question ever asked about ASP.Net but I'm baffled. I have a form wherein my visitor will enter name, address, etc. Then I am POSTing that form via the PostBackUrl property of my Submit button to another page, where the fields are supposed to be all re-formed into new hidden fields, then POSTed again to Paypal. My problem is I cannot get at the values entered by the visitor in the original page. Any time I put in "runat='server'", ASP.Net completely changes the ID of the control, making it impossible to figure out how to access. In the POSTed form I tried Request.Form["_txtFirstName"] and that turned up null. Then I tried ((TextBox)PreviousPage.FindControl("_txtFirstName")).Text and that was null, too. I've tried variations on those. I cannot figure out how I'm supposed to get at these controls. Why does this stuff need to be so difficult?

  • Looking for a way to get HTTP Digest Authentication headers from incoming http requests

    - by duncancarroll
    I've been working on a REST implementation with my existing Cake install, and it's looking great except that I want to use HTTP Digest Authentication for all requests (Basic Auth won't cut it). So great, I'll generate a header in the client app (which is not cake) and send it to my cake install. Only problem is, I can't find a method for extracting that Digest from the request... I've looked through the Cake API for something that I can use to get the Digest Header. You'd think that Request Handler would be able to grab it, but I can't find anything resembling that. There must be another method of getting the digest that I am overlooking? In the meantime I'm writing my own regex to parse it out of the Request... once I'm done I'll post it here so no one has to waste as much time as I did hunting for it.

  • Is there a version of postActionEvent for KeyEvent (specifically for a JTextArea)?

    - by Brian Pelc
    I'm writing a program that contains multiple JTextFields and 2 JTextAreas within an input panel. I have a submit button on the bottom. I have it set up so when a user types something into each field (including the JTextAreas) and hits the Enter key, it updates a text file, and when they press the submit button it updates the file then outputs a new version of it in the local directory. If the user presses Enter in any of the fields, it validates their input, however, I want to re-validate all fields when they press the submit button. Each field (again, JTextAreas included) has it's own validation check within its ActionListener or KeyListener (for the JTextAreas). It's easy enough to use postActionEvent() for the JTextFields, but is there a similar method for the JTextAreas to force fire a KeyEvent? I don't want to duplicate code and consume memory by re-writing the validation for those 2 Components inside the ActionEvent for the JButton. Unfortunately, I can't provide a sample because I'm writing the program on a classified machine (PC).

  • fstream stopping math.h from working

    - by CaptainProg
    I am creating a program in C++ in which I need to read a text file in. I have included the fstream header file, which allows me to open the file, but having added the include, I now receive countless errors relating to math.h functions. Examples: 1>c:\program files\microsoft visual studio 10.0\vc\include\cmath(19): error C2061: syntax error : identifier 'acosf' 1>c:\program files\microsoft visual studio 10.0\vc\include\cmath(19): error C2059: syntax error : ';' Is there any way I can include the text file reading functions of fstream without compromising the math.h functions? And why does this conflict occur anyway? /Edit/ It seems the errors are in the cmath standard header file. It is nothing I have access to, but for the sake of completion, here is the code that is causing the errors: using _CSTD acosf; using _CSTD asinf; using _CSTD atanf; using _CSTD atan2f; using _CSTD ceilf; (etcetera)

  • Ways not to write function headers twice?

    - by mee
    Hi, I've got a C/C++ question, can I reuse functions across different object files or projects without writing the function headers twice? (one for defining the function and one for declaring it) I don't know much about C/C++, Delphi and D. I assume that in Delphi or D, you would just write once what arguments a function takes and then you can use the function across diferent projects. And in C you need the function declaration in header files *again??, right?. Is there a good tool that will create header files from C sources? I've got one, but it's not preprocessor-aware and not very strict. And I've had some macro technique that worked rather bad. I'm looking for ways to program in C/C++ like described here http://www.digitalmars.com/d/1.0/pretod.html

  • Database design: How should I add an information which can apply to several tables

    - by Stefan
    I am constructing a database System using Mysql, this will be an application of about 20 tables. The system contains information on farmers, we work with organic certification and need to record a lot of info for that. In my system, there are related parent-child tables for farmers, producing years and fields/areas - it's a simple representation of the real world in which farmers farm crops on their fields. I now need to add several status flags for each one of these levels: a farmer can be certified, or his field can be, or the specific year can be; each of these flags has several states and can occur a number of times. The obvious solution to this would be to add a child table to every one of these tables, and define the states there. What I wonder if there is an easier way to do this to avoid getting to many tables? Where/how would be best practise to keep that data?

  • iPhone - Make loadView entries fill up parent view?

    - by Eli
    I have a loadView call that basically places one view at the top (like a header) and one at the bottom (like a footer). It's possible via a passed in parameter to not have a header or a footer, to hide them later, or to resize the view. I have all this working, but it's very susceptible to breaking because the views can go in various places of various sizes and all must be manually set to the correct size or they will not use up all the space. I want one in between the two of them that automatically resizes to fill whatever space is not taken by the others. loadView doesn't seem to be able to obtain the size of its parent's frame (or where it's being fit in, exactly), nor do I see an obvious way to just put the center view at a certain position and have its width and height automatically adapted. Any ideas? If I'm not explaining myself well enough and you know Java Swing, think BorderLayout with a BorderLayout.NORTH, BorderLayout.SOUTH, and BorderLayout.CENTER component.

  • How do HTTP proxy caches decide between serving identity- vs. gzip-encoded resources?

    - by mrclay
    An HTTP server uses content-negotiation to serve a single URL identity- or gzip-encoded based on the client's Accept-Encoding header. Now say we have a proxy cache like squid between clients and the httpd. If the proxy has cached both encodings of a URL, how does it determine which to serve? The non-gzip instance (not originally served with Vary) can be served to any client, but the encoded instances (having Vary: Accept-Encoding) can only be sent to a clients with the identical Accept-Encoding header value as was used in the original request. E.g. Opera sends "deflate, gzip, x-gzip, identity, *;q=0" but IE8 sends "gzip, deflate". According to the spec, then, caches shouldn't share content-encoded caches between the two browsers. Is this true?

  • Importing a CSV file without headers into SQL 2008

    - by Luiggi
    I want to import a CSV with 4,8M records into a SQL 2008 table. I'm trying to do it with the Management Studio wizard but it keeps trying to recognize a header row which the CSV doesnt have. I don't find any option to skip this and although I specify the columns myself, the wizard still tries to find a header row and doesnt import anything without it. The structure of the CSV is "818180","25529","Dario","Pereyra","Rosario","SF","2010-09-02" I've also tried alternatives like BULK INSERT but then I find out that with BULK INSERT I can't import files with a text qualifier.

  • How to print lines from a file that have repeated more than six times

    - by Mike
    I have a file containing the data shown below. The first comma-delimited field may be repeated any number of times, and I want to print only the lines after the sixth repetition of any value of this field For example, there are eight fields with 1111111 as the first field, and I want to print only the seventh and eighth of these records Input file: 1111111,aaaaaaaa,14 1111111,bbbbbbbb,14 1111111,cccccccc,14 1111111,dddddddd,14 1111111,eeeeeeee,14 1111111,ffffffff,14 1111111,gggggggg,14 1111111,hhhhhhhh,14 2222222,aaaaaaaa,14 2222222,bbbbbbbb,14 2222222,cccccccc,14 2222222,dddddddd,14 2222222,eeeeeeee,14 2222222,ffffffff,14 2222222,gggggggg,14 3333333,aaaaaaaa,14 3333333,bbbbbbbb,14 3333333,cccccccc,14 3333333,dddddddd,14 3333333,eeeeeeee,14 3333333,ffffffff,14 3333333,gggggggg,14 3333333,hhhhhhhh,14 Output: 1111111,gggggggg,14 1111111,hhhhhhhh,14 2222222,gggggggg,14 3333333,gggggggg,14 3333333,hhhhhhhh,14 What I have tried is to transponse the 2nd and 3rd fields with respect to 1st, so that I can use nawk on the field of $7 or $8 #!/usr/bin/ksh awk -F"," '{ a[$1]; b[$1]=b[$1]","$2 c[$1]=c[$1]","$3} END{ for(i in a){ print i","b[i]","c[i]} } ' file > output.txt

  • ASP.Net navigation tabs like windows tab control

    - by devphil
    I would like to have a webpage something like windows tab control. Each webpage does not lose the contents and data while moving between pages, postbacks, etc. Here is the website design and my idea: [Master Page] "Fruits" "Cars" "Animals" "Operators" clicking on "Fruits" will forwards to "Fruits" page, and the same for other links (tabs) The user works on "Fruits" page searching fruits, fill up some fields, etc. The user then moves to "Cars" page and then builds up his own car by filling some fields, etc and then the user goes back to "Fruits" page again - the user sees the same page where she/he left on "Fruits" page. Please suggest some good ways other than using javascript:history.go(-1). Is this possible to implement?

  • UITableView - iPad - Property '' Not Found on Object of type UITableViewCell

    - by user1797508
    I have added a UITableView prototype Cell into a UIView for an iPad application using StoryBoard in Xcode (targeting iOS6). The problem I'm having is that the labels are not being recognized in my viewController when I try to reference them. In my implementation, I have: - (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath { static NSString *CellIdentifier = @"dashboardMessage"; UITableViewCell *cell = [_tableView dequeueReusableCellWithIdentifier:CellIdentifier]; if (cell == nil) { cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier]; } int row = [indexPath row]; cell.messageSender.text = [_matches valueForKey:@"from"]; } The last line is causing an error: Property 'messageSender' Not Found on Object of type UITableViewCell In the cell's header file I have: @interface DashboardMessageCell : UITableViewCell @property (strong, nonatomic) IBOutlet UILabel *messageSender; @property (strong, nonatomic) IBOutlet UILabel *messageDescr; and the header file is imported into the viewController. I'm lost as to what can be causing the issue, any help would be greatly appreciated. Thanks.

  • Text input for multi-valued attribute

    - by Sean
    I need to create an input form that will allow a user to enter any number of values for a particular attribute. I've tried several approaches, all of which seem to have various levels of failure. The latest model bean looks something like: public class Product { private String name; private String[] tags; ...accessors... } The input fields look something like: <h:inputText id="name" value="#{product.name}"></h:inputText> <h:inputText id="tag0" value="#{product.tag[0]}"></h:inputText> My plan was to allow the user is to use javascript to add additional form fields as needed. This type of setup gives me a 'Target Unreachable' error. What am I missing? I am using JSF 1.1 on WebSphere 6.1

  • overloading new/delete problem

    - by hidayat
    This is my scenario, Im trying to overload new and delete globally. I have written my allocator class in a file called allocator.h. And what I am trying to achieve is that if a file is including this header file, my version of new and delete should be used. So in a header file "allocator.h" i have declared the two functions extern void* operator new(std::size_t size); extern void operator delete(void *p, std::size_t size); I the same header file I have a class that does all the allocator stuff, class SmallObjAllocator { ... }; I want to call this class from the new and delete functions and I would like the class to be static, so I have done this: template<unsigned dummy> struct My_SmallObjectAllocatorImpl { static SmallObjAllocator myAlloc; }; template<unsigned dummy> SmallObjAllocator My_SmallObjectAllocatorImpl<dummy>::myAlloc(DEFAULT_CHUNK_SIZE, MAX_OBJ_SIZE); typedef My_SmallObjectAllocatorImpl<0> My_SmallObjectAllocator; and in the cpp file it looks like this: allocator.cc void* operator new(std::size_t size) { std::cout << "using my new" << std::endl; if(size > MAX_OBJ_SIZE) return malloc(size); else return My_SmallObjectAllocator::myAlloc.allocate(size); } void operator delete(void *p, std::size_t size) { if(size > MAX_OBJ_SIZE) free(p); else My_SmallObjectAllocator::myAlloc.deallocate(p, size); } The problem is when I try to call the constructor for the class SmallObjAllocator which is a static object. For some reason the compiler are calling my overloaded function new when initializing it. So it then tries to use My_SmallObjectAllocator::myAlloc.deallocate(p, size); which is not defined so the program crashes. So why are the compiler calling new when I define a static object? and how can I solve it?

  • Gson serialization depending on field value

    - by Serj Lotutovici
    I have a POJO that is similar to: public class MyGsonPojo { @Expose @SerializedName("value1") private String valueOne; @Expose @SerializedName("value2") private boolean valueTwo; @Expose @SerializedName("value3") private int valueThree; // Getters and other stuff here } The issue is that this object has to be serialized into a json body for a call to the server. Some fields are optional for the request and if I even send it with default and null values, the API responds differently (Unfortunately changing the api is not an option). So basically I need to exclude fields from serialization if any of them is set to a default value. For example if the field valueOne is null the resulting json should be: { "value2" : true, "value3" : 2 } Any idea how to make this a painless effort? I wouldn't want to build the json body manually. Any help would be great. Thank you in advice.

  • VBScript: how to set values from recordset to string

Here is my code: Function getOffice (strname, uname) strEmail = uname WScript.Echo "email: " & strEmail Dim objRoot : Set objRoot = GetObject("LDAP://RootDSE") Dim objDomain : Set objDomain = GetObject("LDAP://" & objRoot.Get("defaultNamingContext")) Dim cn : Set cn = CreateObject("ADODB.Connection") Dim cmd : Set cmd = CreateObject("ADODB.Command") cn.Provider = "ADsDSOObject" cn.Open "Active Directory Provider" Set cmd.ActiveConnection = cn cmd.CommandText = "SELECT physicalDeliveryOfficeName FROM '" & objDomain.ADsPath & "' WHERE mail='" & strEmail & "'" cmd.Properties("Page Size") = 1 cmd.Properties("Timeout") = 300 cmd.Properties("Searchscope") = ADS_SCOPE_SUBTREE Dim objRS : Set objRS = cmd.Execute WScript.Echo objRS.Fields(0) Set cmd = Nothing Set cn = Nothing Set objDomain = Nothing Set objRoot = Nothing Dim arStore Set getOffice = objRS.Fields(0) Set objRS = Nothing End function When I try to run the function, it throws an error "vbscript runtime error: Type mismatch" I presume this means it can't set the string variable with a recordset value. How do I fix this problem?
