  • create a model in create action from a class

    - by Pontek
    As a newbie to rails I can't find how to solve my issue ^^ I want to create a VideoPost from a form with a text field containing a video url (like youtube) I'm getting information on the video thanks to the gem https://github.com/thibaudgg/video_info And I want to save thoses information using a model of mine (VideoInformation). But I don't know how the create process should work. Thanks for any help ! I'm trying to create a VideoPost in VideoPostsController like this : def create video_info = VideoInfo.new(params[:video_url]) video_information = VideoInformation.create(video_info) #undefined method `stringify_keys' for #<Youtube:0x00000006a24120> if video_information.save @video_post = current_user.video_posts.build(video_information) end end My VideoPost model : # Table name: video_posts # # id :integer not null, primary key # user_id :integer # video_information_id :integer # created_at :datetime not null # updated_at :datetime not null My VideoInformation model (which got same attributes name than VideoInfo gem) : # Table name: video_informations # # id :integer not null, primary key # title :string(255) # description :text # keywords :text # duration :integer # video_url :string(255) # thumbnail_small :string(255) # thumbnail_large :string(255) # created_at :datetime not null # updated_at :datetime not null

  • Why are Java primitive types' modifiers `public`, `abstract`, & `final`?

    - by oconnor0
    In the process of doing some reflection on Java types, I came across an oddity that I do not understand. Inspecting int for its modifiers returns public, abstract, and final. I understand public and final, but the presence of abstract on a primitive type is non-obvious to me. Why is this the case? Edit: I am not reflecting on Integer but on int: import java.lang.reflect.Modifier; public class IntegerReflection { public static void main(final String[] args) { System.out.println(String.format("int.class == Integer.class -> %b", int.class == Integer.class)); System.out.println(String.format("int.class modifiers: %s", Modifier.toString(int.class.getModifiers()))); System.out.println(String.format("Integer.class modifiers: %s", Modifier.toString(Integer.class.getModifiers()))); } } The output when run: int.class == Integer.class -> false int.class modifiers: public abstract final Integer.class modifiers: public final

  • Errors in Decimal Calcs within def clean method?

    - by allanhenderson
    I'm attempting a few simple calculations in a def clean method following validation (basically spitting out a euro conversion of retrieved uk product price on the fly). I keep getting a TypeError. Full error reads: Cannot convert {'product': , 'invoice': , 'order_discount': Decimal("0.00"), 'order_price': {...}, 'order_adjust': None, 'order_value': None, 'DELETE': False, 'id': 92, 'quantity': 8} to Decimal so I guess django is passing through the entire cleaned_data form to Decimal method. Not sure where I'm going wrong - the code I'm working with is: def clean_order_price(self): cleaned_data = self.cleaned_data data = self.data order_price = cleaned_data.get("order_price") if not order_price: try: existing_price = ProductCostPrice.objects.get(supplier=data['supplier'], product_id=cleaned_data['product'], is_latest=True) except ProductCostPrice.DoesNotExist: existing_price = None if not existing_price: raise forms.ValidationError('No match found, please enter new price') else: if data['invoice_type'] == 1: return existing_price.cost_price_gross elif data['invoice_type'] == 2: exchange = EuroExchangeRate.objects.latest('exchange_date') calc = exchange.exchange_rate * float(existing_price.cost_price_gross) calc = Decimal(str(calc)) return calc return cleaned_data If the invoice is of type 2 (a euro invoice) then the system should grab the latest exchange rate and apply that to the matching UK pound price pulled through to get euro result. Should performing a decimal conversion be a problem within def clean method? Thanks

    I have create a backgroundworker in an class it works, but if i call and wait until the end run, call it for the second time it will do the same process twice i thinks there is somthing wrong with bw.DoWork += private void button1_Click(object sender, EventArgs e) { nptest.test.start("null", "null"); } namespace nptest { class test { public static void start(string str, string strb) { if (bw.IsBusy != true) { bw.WorkerSupportsCancellation = true; bw.DoWork += (obj, e) => bw_DoWork(str, strb); bw.RunWorkerCompleted += new RunWorkerCompletedEventHandler(bw_RunWorkerCompleted); bw.RunWorkerAsync(); } } private static BackgroundWorker bw = new BackgroundWorker(); private static void bw_DoWork(string str, string strb) { System.Windows.Forms.MessageBox.Show("initializing BackgroundWorker"); } private static void bw_RunWorkerCompleted(object sender, RunWorkerCompletedEventArgs e) { if ((e.Cancelled == true)) { Console.WriteLine("Canceled"); } else if (!(e.Error == null)) { Console.WriteLine("Error: " + e.Error.Message); } bw.Dispose(); } } }

  • need an empty XML while unmarshalling a JAXB annotated class

    - by sswdeveloper
    I have a JAXB annotated class Customer as follows @XmlRootElement(namespace = "http://www.abc.com/customer") public class Customer{ private String name; private Address address; @XmlTransient private HashSet set = new HashSet<String>(); public String getName(){ return name; } @XmlElement(name = "Name", namespace = "http://www.abc.com/customer" ) public void setName(String name){ this.name = name; set.add("name"); } public String getAddress(){ return address; } @XmlElement(name = "Address", namespace = "http://www.abc.com/customer") public void setAddress(Address address){ this.address = address; set.add("address"); } public HashSet getSet(){ return set; } } I need to return an empty XML representing this to the user, so that he may fill the necesary values in the XML and send a request So what I require is : <Customer> <Name></Name> <Address></Address> </Customer> If i simply create an empty object Customer cust = new Customer() ; marshaller.marshall(cust,sw); all I get is the toplevel element since the other fields of the class are unset. What can I do to get such an empty XML? I tried adding the nillable=true annotation to the elements however, this returns me an XML with the xsi:nil="true" which then causes my unmarshaller to ignore this. How do I achieve this?

  • How to define a function which repeats itself when passed an argument

    - by ~unutbu
    Is there an easy way to define a function which repeats itself when passed an argument? For example, I've defined the following function (defun swap-sign () (interactive) (search-forward-regexp "[+-]") (if (equal (match-string 0) "-") (replace-match "+") (replace-match "-")) ) I'd like C-u swap-sign to call swap-sign four times. I've tried (defun swap-sign (&optional num) (interactive) (let ((counter 0) (num (if num (string-to-number num) 0))) (while (<= counter num) (search-forward-regexp "[+-]") (if (equal (match-string 0) "-") (replace-match "+") (replace-match "-")) (setq counter (1+ counter))))) but C-u swap-sign still only runs swap-sign (or perhaps more precisely, the body of the while-loop) once. I'm guessing it is because if num is not the right way to test if num is an empty string. Am I on the right track, or is there a better/easier way to extend swap-sign?

  • Parameter attributes in c#

    - by ng
    How can I do the following with c# attributes. Below is a snippet of Java that annotates parameters in a constructor. public class Factory { private final String name; private final String value; public Factory(@Inject("name") String name, @Inject("value") String value) { this.name = name; this.value = value; } } From looking at c# annotations it does not look like I can annotate parameters. Is this possible?

  • Java generic return tpye

    - by Colby77
    Hi, I'd like to write a method that can accept a type param (or whatever the method can figure out the type from) and return a value of this type so I don't have to cast the return type. Here is a method: public Object doIt(Object param){ if(param instanceof String){ return "string"; }else if(param instanceof Integer){ return 1; }else{ return null; } } When I call this method, and pass in it a String, even if I know the return type will be a String I have to cast the return Object. This is similar to the int param. How shall I write this method to accept a type param, and return this type?

  • Executing a process in windows server 2003 and ii6 from code - permissions error

    - by kurupt_89
    I have a problem executing a process from our testing server. On my localhost using windows XP and iis5.1 I changed the machine.config file to have the line - I then changed the login for iis to log on as local system account and allow server to interact with desktop. This fixed my problem executing a process from code in xp. When using the same method on windows server 2003 (using iis6 isolation mode) the process does not get executed. Here is the code to execute the process (I have tested the inputs to iecapt through the command line and an image is generated) - public static void GenerateImageToDisk(string ieCaptPath, string url, string path, int delay) { url = FixUrl(url); ieCaptPath = FixPath(ieCaptPath); string arguments = @"--url=""{0}"" --out=""{1}"" --min-width=0 --delay={2}"; arguments = string.Format(arguments, url, path, delay); ProcessStartInfo ieCaptProcessStartInfo = new ProcessStartInfo(ieCaptPath + "IECapt.exe"); ieCaptProcessStartInfo.RedirectStandardOutput = true; ieCaptProcessStartInfo.WindowStyle = ProcessWindowStyle.Hidden; ieCaptProcessStartInfo.UseShellExecute = false; ieCaptProcessStartInfo.Arguments = arguments; ieCaptProcessStartInfo.WorkingDirectory = ieCaptPath; Process ieCaptProcess = Process.Start(ieCaptProcessStartInfo); ieCaptProcess.WaitForExit(600000); ieCaptProcess.Close(); }

  • is putting N in front of strings in scripts considered a "best practice"?

    - by jcollum
    Let's say I have a table that has a varchar field. If I do an insert like this: INSERT MyTable SELECT N'the string goes here' Is there any fundamental difference between that and: INSERT MyTable SELECT 'the string goes here' My understanding was that you'd only have a problem if the string contained a Unicode character and the target column wasn't unicode. Other than that, SQL deals with it just fine and converts the string with the N'' into a varchar field (basically ignores the N). I was under the impression that N in front of strings was a good practice, but I'm unable to find any discussion of it that I'd consider definitive. Title may need improvement, feel free.

  • How can I tell when the Text of a System.Windows.Forms.GroupBox wraps to the next line?

    - by fre0n
    I'm creating a GroupBox at runtime and setting its Text property. Usually, the text is only on one line, but sometimes it wraps. The problem is that the controls contained in the GroupBox cover up the GroupBox's text. What I'd like to do is determine if and when the text wraps. Specifically, I'd like to determine how much extra height the wrapped text takes up as compared to a single line. That way, I can reposition the GroupBox's controls and adjust its height. Initially, I thought I'd do this by calling the GroupBox's CreateGraphics() method, and using the Graphics to measure the string. Something like this: private void SetGroupBoxText(GroupBox grp, string text) { const int somePadding = 10; Graphics g = grp.CreateGraphics(); SizeF textSize = g.MeasureString(text, grp.Font); if (textSize.Width > (grp.Width - somePadding)) { // Adjust height, etc. } } The problem is that the size generated by g.MeasureString(text, grp.Font) doesn't seem to be accurate. I determined that it wasn't accurate by putting enough of a single character to cause a wrap, then measuring the resulting string. For example, it took 86 pipes (|) to until a wrap happened. When I measured that string, its width was ~253. And it took 16 capital W's to force a wrap - its string had a width of ~164. These were the two extremes that I tested. My GroupBox's width was 189. (a's took 29 and had a width of ~180, O's took 22 and had a width of ~189) Does anyone have any ideas? (hacks, WinAPI, etc. are welcome solutions)

  • Not sure I am using inheritance/polymorphism issue?

    - by planker1010
    So for this assignment I have to create a car class(parent) and a certifiedpreowned (child) and I need to have the parent class have a method to check if it is still under warranty. *checkWarrantyStatus(). that method calls the boolean isCoveredUnderWarranty() to veryify if the car still has warranty. My issue is in the certifiedpreowned class I have to call the isCoveredUnderWarranty() as well to see if it is covered under the extended warranty and then have it be called via the checkWarrantyStatus() in the car method. I hope this makes sense. So to sum it up I need to in the child class have it check the isCoveredUnderWarranty with extended warranty info. Then it has to move to the parent class so it can be called via checkWarrantyStatus. Here is my code, I have 1 error. public class Car { public int year; public String make; public String model; public int currentMiles; public int warrantyMiles; public int warrantyYears; int currentYear =java.util.Calendar.getInstance().get(java.util.Calendar.YEAR); /** construct car object with specific parameters*/ public Car (int y, String m, String mod, int mi){ this.year = y; this.make = m; this.model = mod; this.currentMiles = mi; } public int getWarrantyMiles() { return warrantyMiles; } public void setWarrantyMiles(int warrantyMiles) { this.warrantyMiles = warrantyMiles; } public int getWarrantyYears() { return warrantyYears; } public void setWarrantyYears(int warrantyYears) { this.warrantyYears = warrantyYears; } public boolean isCoveredUnderWarranty(){ if (currentMiles < warrantyMiles){ if (currentYear < (year+ warrantyYears)) return true; } return false; } public void checkWarrantyStatus(){ if (isCoveredUnderWarranty()){ System.out.println("Your car " + year+ " " + make+ " "+ model+ " With "+ currentMiles +" is still covered under warranty"); } else System.out.println("Your car " + year+ " " + make+ " "+ model+ " With "+ currentMiles +" is out of warranty"); } } public class CertifiedPreOwnCar extends Car{ public CertifiedPreOwnCar(int y, String m, String mod, int mi) { super(mi, m, mod, y); } public int extendedWarrantyYears; public int extendedWarrantyMiles; public int getExtendedWarrantyYears() { return extendedWarrantyYears; } public void setExtendedWarrantyYears(int extendedWarrantyYears) { this.extendedWarrantyYears = extendedWarrantyYears; } public int getExtendedWarrantyMiles() { return extendedWarrantyMiles; } public void setExtendedWarrantyMiles(int extendedWarrantyMiles) { this.extendedWarrantyMiles = extendedWarrantyMiles; } public boolean isCoveredUnderWarranty() { if (currentMiles < extendedWarrantyMiles){ if (currentYear < (year+ extendedWarrantyYears)) return true; } return false; } } public class TestCar { public static void main(String[] args) { Car car1 = new Car(2014, "Honda", "Civic", 255); car1.setWarrantyMiles(60000); car1.setWarrantyYears(5); car1.checkWarrantyStatus(); Car car2 = new Car(2000, "Ferrari", "F355", 8500); car2.setWarrantyMiles(20000); car2.setWarrantyYears(7); car2.checkWarrantyStatus(); CertifiedPreOwnCar car3 = new CertifiedPreOwnCar(2000, "Honda", "Accord", 65000); car3.setWarrantyYears(3); car3.setWarrantyMiles(30000); car3.setExtendedWarrantyMiles(100000); car3.setExtendedWarrantyYears(7); car3.checkWarrantyStatus(); } }

  • How do I get class of an internal static class in another assembly?

    I have a class C in Assembly A like this: internal class C { internal static string About_Name { get { return "text"; } ... } I have about 20 such static properties. Is there a way, in an outside assembly, without using friend assembly attribute (.Net reflection only), get class C so I can invoke any of the static string properties like this: Class C = <some .Net reflection code>; string expected = C.About_Name; If that is not possible, a .Net reflection code to get the string property value directly will suffice, but not ideal.

  • ASP.Net Custom Paging (w/ C#)

    - by André Alçada Padez
    Cenario: I have a GridView bound to a DataSource, every column is sortable. my main query is something like: select a, b, c, d, e, f from table order by somedate desc i added a filter form where i can define values to each one of the fields and get the results of a where form. As a result from this, i had to do a custom sorting so that when i sort by a field, i am sorting the filtered query and not the main one. Now i have to do custom paging, for the same reason, but i don't understand the philosophy of it: I want to guarantee that i can: filter the results sort by a column when i click on page 2, i get page two of the filtered and sorted results I don't know what i have to do, so i can bind the GV with this. My sorting Method, that is working just fine looks something like: string condition = GetConditions(); //gets a string like " where a>1 and b>2" depending on the filter the user defines string query = "select a, b, c, d, e, f from table "; string direction = (e.SortDirection == SortDirection.Ascending)? "asc": "desc"; string order = " order by " + e.SortExpression + " " + direction; UtilizadoresDataSource.SelectCommand = query + condition + order; i've never done custom paging, i am trying: GetConditions() //no problem here How can i find out how the GridView is sorted (by what field and sortingorder)? thank you very much

I have the following while loop (nested down several levels of other while loops and if statements) which calls getline, but my output statement which is the first code line in the while loop's block of code tells me it is reading the same line over and over again, which explains why my output file doesn't contain the right data when my program is finished. while (getline(file_handle, buffer_str)) { cout<< buffer_str <<endl; cin.get(); if ((buffer_str.find(';', 0) != string::npos) && (buffer_str.find('\"', 0) != string::npos)) { //we're now at the end of the 'exc' initialiation statement buffer_str.erase(buffer_str.size() - 2, 1); buffer_str += '\n'; for (size_t i = 0; i < pos; i++) { buffer_str += ' '; } buffer_str += "throw(exc);\n"; for (size_t i = 0; i < (pos - 3); i++) { buffer_str += ' '; } buffer_str += '}'; } else if (buffer_str.find(search_str6, 0) != string::npos) { //we're now at the second problem line of the first case buffer_str += " {\n"; output_str += buffer_str; output_str += '\n'; getline(file_handle, buffer_str); //We're now at the beginning of the 'exc' initialiation statement output_str += buffer_str; output_str += '\n'; while (getline(file_handle, buffer_str)) { if ((buffer_str.find(';', 0) != string::npos) && (buffer_str.find('\"', 0) != string::npos)) { //we're now at the end of the 'exc' initialiation statement buffer_str.erase(buffer_str.size() - 2, 1); buffer_str += '\n'; for (size_t i = 0; i < pos; i++) { buffer_str += ' '; } buffer_str += "throw(exc);\n"; for (size_t i = 0; i < (pos - 3); i++) { buffer_str += ' '; } buffer_str += '}'; } output_str += buffer_str; output_str += '\n'; if (buffer_str.find("return", 0) != string::npos) { getline(file_handle, buffer_str); output_str += buffer_str; output_str += '\n'; about_to_break = true; break; //out of this while loop } } } if (about_to_break) { break; //out of the level 3 while loop (execution then goes back up to beginning of level 2 while loop) } output_str += buffer_str; output_str += '\n'; } Because of this problem, my if statement and then my else statement in my loop are not functioning as they should, and it doesn't break out of that loop when it should (though it eventually does break out of it, but I don't know exactly how yet). Anyone have any idea what could be causing this problem?? Thanks in advance.

  • PHP - Using strcpsn() to protect against SQL injection?

    - by MichaelMitchell
    I am making a sort of form validation system and I need to check the SQL database to see if the username is already there. So, my question, is it effective to use a little if statement like this to protect against an attack? if (strcspn($string, "/\?!@#$%^&*()[]{}|:;<>,.\"\'-+=" == strlen($string)){ return true; } So essentially, if the string contains any of these characters, "/\?!@#$%^&*()[]{}|:;<>,.\"\'-+=", then the length will not equal that of the original $string. I am just wondering if this is sufficient to protect, or if there is more that I must do. Thanks.
