Now you re ready to write a view function that will perform a basic search. Here s the code, which will go into views.py below the import statements you added: def search(request): query = request.GET['q'] results = FlatPage.objects.filter(content__icontains=query) template = loader.get_template('search/search.html') context = Context({ 'query': query, 'results': results }) response = template.render(context) return HttpResponse(response) Let s break this down line by line. First, you re defining a Python function using the keyword def. The function s name is search, and it takes one argument named request. This will be an HTTP request (an instance of the class django.http.HttpRequest), and Django will ensure that it s passed to the view function when needed. Next, look at the HTTP GET variable q to see what the user searched for. Django automatically parsed the URL, so a URL like this: http://www.example.com/search q=foo results in an HttpRequest whose GET attribute is a dictionary containing the name q and the value foo. Then you can read that value out of it just as you would access any Python dictionary. The next line does the actual search. The FlatPage class, like nearly all Django data models, has an attribute named objects that can be used to perform queries on that model. In this case, you want to filter through all of the flat pages, looking for those whose contents contain the search term. To do this, you use the filter method and the argument content__ icontains=query, storing the results in a variable named results. This will provide a list of FlatPage objects that matched the query.

beginning of function blocks, before any other statement. If you are coming from Java or C++ development, you may struggle getting used to this.

Typically, the report is executed with Query_depth set to 2 and all other options set either as ALL or Y. This will yield the most useful report for prerequisite requirement searching. The query must be run by the apps user account, like this: $sqlplus apps/apps_password \ @adphrept.sql 2 ALL ALL ALL ALL ALL \ ALL ALL ALL ALL N N N N N patches.txt

The first three columns, which will be visible in the GtkTreeView, are string types. The fourth column, the message, will not be visible in the tree, but it s useful to store it in the GtkTreeModel so that it s accessible when this list item is selected. The final column will hold pointers to the struct url_data instances and is a pointer type. This is similar to MESSAGE_COLUMN; it s included

As you ll see shortly, a Django data model has special attributes called fields, which usually correspond to the names of the columns in the database. When you use Django s object-relational mapper (ORM) to run a query, each argument in the query comprises a combination of a field name and a lookup operator, separated by double underscores. In this case, the field name is content because that s the field on the FlatPage model that represents the page s contents (each FlatPage also has fields named title, url, and so on). The lookup operator is icontains, which checks whether the value in that column contains the string you ve passed to it. The i at the front means the operator performs a case-insensitive lookup, so a query for hello would match both hello and Hello, for example. The Django ORM supports a large number of other lookup operators, many of which you ll see in action throughout this book.

only as ancillary data rather than something that will actually be shown in the tree With a valid model, I can now create the GtkTreeView to display it: tree = gtk_tree_view_new_with_model(GTK_TREE_MODEL(list_store)); Then I need to add columns to the GtkTreeView This includes creating cell renderers to draw each element in the tree and associating these renderers with the data stored in the tree model I need to do this three times, one for each visible column in the GtkTreeView, but I will declare only one GtkCellRenderer and GtkTreeViewColumn variable and reuse them: GtkTreeViewColumn *col; GtkCellRenderer *rend; Each column is associated with a renderer These renderers have properties that are set to the values stored in the GtkTreeModel When you create a column, you associate the renderer, and tell it where to get the values for each property it uses.

To search the report for a specific patch or bug, the following may be executed against the generated file: grep [patch or bug number] patches.txt If the grep command returns results, the patch or bug fix has been applied to the instance. For example, to test for existence of patch 3410000, check whether the following command returns any data: $grep 3410000 patches.txt
