(
I am very new to programming so please excuse my ignorance but how would I retrieve the value 'loyalty' at category_list index 1? Using Flutter (Dart) I have tried the documentation but alas have found myself down the rabbit hole.
I have no issue with the code below when retrieving an image from the question document and I'm trying to achieve the same result.
final questions = await _firestore
.collection('questions')
.document(getCategory)
.collection(pullLeadership)
.document('question')
.get();
newQuestion = questions.data['$questionNumber'];
Should be:
category = categories.data["category_list"][1];

Long time reader, first time poster, please be gentle.
I've been working on a web app using Flask and SQLAlchemy that allows users to review and comment on MMA fights. I have a list of fights in a SQL table appropriately named "fights" and I'm trying to use dynamic routing to filter through the data. I have a list of all the fights on one route like so:
#app.route('/ufc251')
#login_required
def ufc251():
return render_template('ufc251.html', fights=Fight.query.all())
which helped me make a slick page with all the fights listed, and then made another route for info on individual fights like so:
#app.route('/fight/<int:id>')
#login_required
def fight(id):
id = Fight.query.filter_by(id=id).first_or_404()
return render_template('fight.html')
so far, so good. If I click on a fight from the main page i get sent to a url fightsite/fights/<fight_id>, which is perfect. The problem that I'm having is that I can't for the life of me figure out how to call the data from the row for a single fight. If i change my route to:
#app.route('/fight/<int:id>')
#login_required
def fight(id):
id = Fight.query.filter_by(id=id).first_or_404()
return render_template('fight.html', fight=Fight.query.filter_by(id=id).first())
I get the error
sqlalchemy.exc.ArgumentError: Object <Fight 1> is not legal as a SQL literal value
but if i give id a value (i.e. id=1) it will display the data from the first row in my fights table, so i feel like the problem is in the (id=id) part, but after hours of scouring the internet, I can't seem to find a solution.
Any help would be greatly appreciated. And yes, I've read the other StackOverflow article on this subject, however the answer doesn't seem to apply to this situation.
Thank you in advance!
I figured it out, however I decided I'd leave the question in case anybody else has this issue.
i changed:
#app.route('/fight/<int:id>')
#login_required
def fight(id):
id = Fight.query.filter_by(id=id).first_or_404()
return render_template('fight.html', fight=Fight.query.filter_by(id=id).first())
to:
#app.route('/fight/<int:id>')
#login_required
def fight(id):
id = Fight.query.filter_by(id=id).first_or_404()
return render_template('fight.html', fight=Fight.query.filter_by(id=id.id).first())
because initially it was passing the argument 'fight_1' instead of just '1'. I hope nobody else has to spend this long trying to solve the same problem!
The use of id to hold a Fight confuses things. Then there's the double query when one would suffice.
Consider changing
id = Fight.query.filter_by(id=id).first_or_404()
return render_template('fight.html', fight=Fight.query.filter_by(id=id).first())
to
fight = Fight.query.filter_by(id=id).first_or_404()
return render_template('fight.html', fight=fight)
I have been struggling with this simple query in django. I have checked a lot over internet. I tried using similar syntax - yet no luck.
In my application on html page I need to display some specific record. And for that i want to use parameterized select statement. But the query is not working..
I have checked id2 is getting correct value from previous html page..
And I know I can use APIs but for my databases classes I need to use raw queries in my application.
Can someone please help me here...
def details(request, id2):
temp = 'test3'
data = Posts.objects.raw('''select * from posts_posts where posts_posts.id = %s ''', id2)
context ={
'post' : data,
If you run that code you will see an error, since that is not the correct format for a call to raw. If you can't see the error output anywhere, then you have yet another problem for another post.
The correct format for raw is: .raw(sql, iterable-values), like this:
posts = Posts.objects.raw("select * ..", [id2, ]) # or use (id2,) for a tuple
<RawQuerySet: select * from ... where id = 5>
To get the actual list, since that just gives you a Query, you need to evaluate it somehow:
posts_list = list(posts)
first_post = posts[0]
Be careful, if you don't evaluate the QuerySet then it can be re-run a second time. Please convert it to a list() before doing further operations on it.
I have been using soapui opensource for a small period and not yet good at groovy script. Please help figuring out the following issue:
I get response from the previous test step. Lets say Response1 and need to parse it in order to get Id value from it. Then I need to add string DomainId before this id so that it looked smth like this:
DomainId_234565
and tranfer it to next request.
Could someone please explain how to do it with groovy? (I guess it is the best way to do it)
Thank you
Managed to resolve myself. Add property step response where I store response from previous step and also added property trasfer step to put response to the property. Then I add groovy script: def groovyUtils = new com.eviware.soapui.support.GroovyUtils( context ) def holder = groovyUtils.getXmlHolder("Properties#response") return "DomainId_ " + holder.getNodeValue("//*:Id") and it works, returns the correct value
how to make such query in django.
I have Site model where I can find relation to the topic model. In topic model I can fing relation to the post model. I want to extract post from a site having information only about site, not a topic. What is more posts have to starts with query.
query = request.GET.get('query','')
iweb_obj = IWeb.objects.get(id=iweb_id)
topics = Topic.objects.filter(iweb=iweb_obj)
iweb_posts = []
for t in topics:
posts = Post.objects.filter(topic=t)
for p in posts:
iweb_posts.append(p)
iweb_posts = iweb_.filter(content__istartswith=query)
I have an error that iweb_posts isnt query set and I cant make such action. It is quite obvious, however I do not have idea how to make it works ? I've heard that I can use filter(**kwargs) but I do not know how to use it ?
Your logic looks a little funky since you're overwriting posts each time in the topic loop. You can accomplish what you need without loops and lists using only query set filters (I've added an __in filter, for example):
query = request.GET.get('query','')
iweb_obj = IWeb.objects.get(id=iweb_id)
topics = Topic.objects.filter(iweb=iweb_obj)
iweb_posts = Post.objects.filter(topic__in=topics).filter(content__istartswith=query)
I want to implement search functionality, So my requirement is I want to search some keyword in body tag in all content page. I do not know how I can search keyword in body tag in Sitecore. Please guide me?
As Anton outlined, the concept of searching the Body tag is wrong for Sitecore. You want to think in terms of Content in fields of Items. Sitecore's ContentSearch is how you can achieve this.
Sitecore comes with default indexes out-of-the-box that you should use for the search. You should rebuild these via the Index Manager in the Content Editor and then base your search on the basic example I've outlined for you below.
public IEnumerable<Item> Search(string searchterm)
{
string indexName = "sitecore_web_index";
using (var index = ContentSearchManager.GetIndex(indexName).CreateSearchContext())
{
var predicate = PredicateBuilder.True<SearchResultItem>();
IQueryable<SearchResultItem> query = index.GetQueryable<SearchResultItem>().Where(i => i.Content.Contains(searchterm)).Filter(predicate);
var searchResults = query.GetResults();
foreach (var hit in searchResults.Hits)
{
yield return hit.Document.GetItem();
}
}
}
jRobbins's answer is sensible (he get's my upvote). However, it is technically possible to index the content of the body tag. I would be cautious with this. I've seen it working well, but I've also seen it completely destroy the performance of a site.
The approach involves the creating a computed field in your index. You populate the computed field by making a web request to your newly published page and scraping the response body tag.
Here's are a couple of module that more or less does that:
https://github.com/efocus-nl/sitecorewebsearch
https://github.com/hermanussen/sitecore-html-crawler
If you can accept something a little less accurate, then you could loop through each of the components on your page and extract content from their datasources. That approach is discussed in this video:
