问题 I am using below code to add meta keywords - in view.py @template_render("mysite/category.html") def category(request, slug): slug = slug.lower() product_type = local_settings.CATEGORY_NAME_TO_ID.get(slug, False) if not product_type: raise Http404 products = models.Product.objects.active().filter(product_type = product_type).all() return { 'products' : products, 'slug' : slug, 'key':'wholesale ipad, ipad with retina display, ipad mini, ipad 3, ipad 2',} And in template file - {% extends "base

问题 I would like to crawl/check multiple websites(on same domain) for a specific keyword. I have found this script, but I can't find how to add the specific keyword to be search for. What the script needs to do is find the keyword, and give the result in which link it was found. Could anyone point me to where i could read more about this ? I have been reading scrapy's documentation, but I can't seem to find this. Thank you. class FinalSpider(scrapy.Spider): name = "final" allowed_domains = [

问题 PhpStorm is highlighting the following namespace as an error. <?php namespace App\Http\Controllers\Public; Error: Expected: identifier In general. Are reserved keywords like public , function , class not acceptable for namespacing? 回答1: The PHP manual hints that as of PHP 7.0.0 these keywords are allowed as property, constant, and method names of classes, interfaces and traits, except that class may not be used as constant name , which also incorporate the requested keyword public . List of

问题 I have to store a set of related keywords inside a database. As of now, I am thinking of using the following: To store the keywords themselves: CREATE TABLE keywords( id int(11) AUTO_INCREMENT PRIMARY KEY, word VARCHAR(255) ); To store the relations (stores the ids of the related keywords): CREATE TABLE relatedkeywords( id int(11) AUTO_INCREMENT PRIMARY KEY, keyword1 int(11), keyword2 int(11), FOREIGN KEY (keyword1) REFERENCES keywords(id), FOREIGN KEY (keyword2) REFERENCES keywords(id) ); Is

问题 So I'm making a script to check the keyword density of a page based off the URL the user submits and I have been using strip_tags but it doesn't seem to be completely filtering the javascript and other code from the actual word content on the site. Is there a better way to filter between the code content on a page and the actual word content? if(isset($_POST['url'])){ $url = $_POST['url']; $str = strip_tags(file_get_contents($url)); $words = str_word_count(strtolower($str),1); $word_count =

问题 I've got a database with video ids and N keywords for each video. I made a table with 1 video ID and 1 keyword ID in each row. What's the easiest way to order keywords by frequency? I mean to extract the number of times a keyword is used and order them. Is it possible to do that with sql or do I need to use php arrays? Thanks 回答1: I don't see the need for a join here. Simply list all the keywords along with the number of times the keyword appears, ordered from most frequent to less frequent.

问题 How do I edit JPG File Title, Subject, Comments, and Tags/Keyowrds?* I have already tried asking this question here: The Exif information provided was helpful, but in the end did not actually solve the real riddle I was working on. So I'll take another angle at describing the desired result: I want my VB.NET app to allow me to edit the following details of a Jfile (see image): Title, Subject, Comments, and Tags/Keyowrds I had a handy image to include but not enough points to post it. Weak.

问题 I recently removed a private specified from a class definition because it was at the top, immediately after the class keyword: class MyClass { private: int someVariable; // ... I thought that it was redundant. A coworker disagreed with this, saying that it effectively "hid" the private nature of the data. Most of our legacy code explicitly states the access specifiers, and usually intermingles them inconsistently throughout the definition. Our classes also tend to be very large. I'm trying to

问题 I'd like to add a new keyword to Python and @EliBendersky's wonderful answer explains how to do this by changing the code and re-distributing the Python compiler. Is it possible to introduce a new keyword without changing the compiler code? Perhaps introduce it through a library? Edit: For example, I'd like to add a shorthand for regex matching by adding a keyword like matches that can be used like: "You can't take the sky from me" matches '.+sky.+' I can add new, custom behavior using AST

问题 Simple question. I made a class called Tester1 which extends another called Tester2. Tester2 contains a public string called 'ABC'. Here is Tester1: public class Tester1 extends Tester2 { public Tester1() { ABC = "Hello"; } } If I instead change line 5 to super.ABC = "Hello"; am I still doing the exact same thing? 回答1: Yes. There's only one ABC variable within your object. But please don't make fields public in the first place. Fields should pretty much always be private. If you declared a
