    <p>I've used flask before and I've had working form validation but for some reason its not working for my new app. Here is the basic code of the form </p> <pre><code>from flask.ext.wtf import Form, TextField, TextAreaField, SubmitField, validators,ValidationError class subReddit(Form): subreddit = TextField('subreddit', [validators.Required('enter valid subreddit')]) next = SubmitField('next') change = SubmitField('change') user = TextField('user', [validators.Required('enter valid user')]) fetch = SubmitField('fetch comments') </code></pre> <p>I have subreddit as the validation field, so if its empty, I want it to throw an error and reload the page. </p> <p>Here is the html</p> <pre><code>&lt;form class='sub' action="{{ url_for('sr') }}" method='post'&gt; {{ form.hidden_tag() }} &lt;p&gt; if you want to enter more than one subreddit, use the + symbol, like this: funny+pics+cringepics &lt;p&gt; &lt;br/&gt; {% for error in form.subreddit.errors %} &lt;p&gt;{{error}}&lt;/p&gt; {% endfor %} {{form.subreddit.label}} {{form.subreddit}} {{form.change}} &lt;/form&gt; </code></pre> <p>I have CSRF_ENABLED=True in my routes.py as well. What am I missing? When I leave the subredditfield empty and click change, it just reloads the page, no errors. This is an issue because whatever is in the field will get recorded in my database, and it can't be empty. </p> <p>EDIT</p> <pre><code>@app.route('/index',methods=['GET','POST']) @app.route('/',methods=['GET','POST']) def index(): form = subReddit() rand = random.randint(0,99) sr = g.db.execute('select sr from subreddit') srr = sr.fetchone()[0] r = requests.get('http://www.reddit.com/r/{subreddit}.json?limit=100'.format(subreddit=srr)) j = json.loads(r.content) pic = j['data']['children'][rand]['data']['url'] title = None if form.validate_on_submit(): g.db.execute("UPDATE subreddit SET sr=(?)", [form.subreddit.data]) print 'validate ' if j['data']['children'][rand]['data']['url']: print 'pic real' sr = g.db.execute('select sr from subreddit') srr = sr.fetchone()[0] r = requests.get('http://www.reddit.com/r/{subreddit}.json?limit=100'.format(subreddit=srr)) pic = j['data']['children'][rand]['data']['url'] title = str(j['data']['children'][rand]['data']['title']).decode('utf-8') return render_template('index.html',form=form,srr=srr,pic=pic,title=title) else: print 'not valid pic' return render_template('index.html',form=form,srr=srr,pic=pic) else: print 'not valid submit' return render_template('index.html',form=form,srr=srr,pic=pic) return render_template('index.html',form=form,srr=srr,pic=pic) </code></pre>

    1. COCan you show the code from the view that actually uses the form?

    2. COI will add what I have in an edit, but I am messing with it a lot because nothing is working. When I enter an invalid subreddit, instead of reloading the page or anything, it just throws an error at the pic variable because it cant get json from an invalid sub

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.
