converter

问题 I want to convert my input into a timestamp value. I have only found a dateconverter in examples. Are there any best practises? Thank you Update: I want to save a birthday of a user but my backend requires a timestamp value. And I have problems with binding it to my jsf frontend.. Maybe a link to an example would be helful :-) I tried it as follows: public void setBday(Date bday) { member.setBirthday(new Timestamp(bday.getTime())); } public Timestamp getBday() { return member.getBirthday(); }

问题 My JSF pages display DateTime from managed beans in this format: "MM/dd/yyyy h:mm a" I want avoid duplicate converter declaration in different pages: <f:convertDateTime type="both" pattern="MM/dd/yyyy h:mm a" dateStyle="short" timeStyle="medium" /> Is there a way to make the above converter default for all DateTime fields? (Experience with JSF 2: 2 months.) 回答1: Just extend the DateTimeConverter class behind <f:convertDateTime> and set the defaults in the constructor. @FacesConverter(

问题 I am currently inserting data in my django models using csv file. Below is a simple save function that am using: def save(self): myfile = file.csv data = csv.reader(myfile, delimiter=',', quotechar='"') i=0 for row in data: if i == 0: i = i + 1 continue #skipping the header row b=MyModel() b.create_from_csv_row(row) # calls a method to save in models The function is working perfectly with ascii characters. However, if the csv file has some non-ascii characters then, an error is raised:

问题 So I'm working on a project that has inputs from a fairly clunky database that I have zero control over what type of data it gives me. It basically gives me a string that has numbers in it including decimals. " take 0.5 Tab by mouth 2 times daily." Whenever it says tab I want to grab the number before tab and convert it to double format. I know how to use cdbl to convert it once I have the string "0.5" but how I get just that string is kind of difficult since InStr only searches left to right

问题 I am using <f:convertNumber> tag to convert a decimal input. <f:convertNumber minFractionDigits="2" /> But it's accepting trailing alphabatic characters. For example, if I input 12345.1234AAA it converts to 12345.123 . I would like it to throw a conversion error on that instead of trimming the alphabetic characters. How can I achieve this? 回答1: This simply is the standard behavior of java.text.NumberFormat as used by <f:convertNumber> : It trims all entries after the first not-allowed

问题 How can I use Python to convert a qcow2 image file into a raw image file? I know of qemu-img , but I'm curious about any Python libraries that might allow me to avoid asking my users to install that tool. It's not packaged with a default Fedora install, and that's what I'm developing for. If there are no other options however, I'll use qemu-img . 回答1: It seems that qemu-img is a necessity for converting qcow2 image files to raw images. I did not find a solution that avoided calling on this
