    <p>I have created a separate app for a feature I am planning to extend using this 3rd party app and I don't intend to touch its code.</p> <p>The view I want to extend, posts a question or gets a form for a user to ask a question. I want to use this view to post an article. The form it uses is different. </p> <p>Psuedo code below:</p> <pre><code>post_question_view(request) If user is authenticated and read only, redirect somewhere else. form = form.Askquestionform(request.REQUEST) ( I would like to do form = form.AskArticleform()) If the request is post and form is valid, get clean data. (The article will include additional data) If user is authenticated, draft a question and write the question to the database. Generate a new-question-posted signal and redirect. (I don't have to make any changes here I guess) If user is not authenticated, create anonymous question, write it to the database and redirect to the login page. If the request is get fill in the form intial and render to ask_question.html (I would like to render to ask_article.html) </code></pre> <p>Most of the code is there with minor altercations that needs to be done. I need to fill in few blanks and add some new blanks to the existing code. How do I do this using the dry princliple? </p> <ol> <li>Should I create a wrapper for the 2 functions and based on the request, call the appropriate one? </li> <li>Is it possible to use a decorator? The form will contain new fields so without modifying the current view, I don't think its possible. </li> <li>Or is there no other way than to copy this view to my app and make the modifications? </li> </ol>

    1. COYou should really post some real code example, as options may vary quite a bit depending on the 3rd party view implementation.

    2. COThe view you are trying to depict here, is it written by you or the 3rd party app? With such ambiguous code its tough, could you get more close to the real scenario?

    3. CODo the source function (which you want to extend) has necessary formal parameters to pass what you want (e.g. different form)?

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
