I have 1000 browser tabs open and I don't seem to be able to find the expected info.
server.js
In the server, I'm running this to get the data from my neo4j database:
app.get('/ios', async (req, res) => {
try {
const iosUberResult = await session.run(`MATCH p=(ios:IOS {name: 'UofO'})-->(ios2:CampBus)<--(ios3:SchColUnit)<--(ios4:Dept)
With collect(p) as p2
CALL apoc.convert.toTree(p2, true, {
nodes: {IOS: ['name'], CampBus: ['name'], SchColUnit: ['name'], Dept: ['name']}
}) yield value
Return value`);
const iosUberArr = iosUberResult.records.map(({_fields}) => {
return {iosUber: _fields[0] };
});
res.render('ios', {
iosUber:iosUberArr
});
console.log(iosUberArr); //this does not show the entire json as hoped
} catch(e) {
console.log("Something went wrong", e)
}
});
cypher query result
It should be noted that the cypher query seen above returns valid json. Here is the nested json hierarchy:
Parent:UofO
Child: CampBus
Grand Child: SchColUnit
Great Grand Child: Dept
Here is the value returned when run on neo4j browser:

ios.ejs
On my ios.ejs page, I have the following where I try to port the data iosUber into a form:
<form id="Is-LocatedForm" method="get" class="lb-lg form-margin ">
<label>Level 1</label><br>
<select id="" class="form-control" type="text">
<% iosUber.forEach(function(lev){ %>
<option ><%= lev.name %></option>
<% }) %>
</select>
<br>
<label>Level 2</label><br>
<select id="" class="form-control" type="text">
<% iosUber.has_campbus.forEach(function(lev){ %>
<option ><%= lev.name %></option>
<% }) %>
</select>
<br>
<label>Level 3</label><br>
<select id="" class="form-control" type="text">
<% iosUber.has_schcolunit.forEach(function(lev){ %>
<option ><%= lev.name %></option>
<% }) %>
</select>
<br>
<label>Level 4</label><br>
<select id="" class="form-control" type="text">
<% iosUber.has_dept.forEach(function(lev){ %>
<option><%= lev.name %></option>
<% }) %>
</select>
</form>
This rendering from server to client does not work because I don't understand how to access the nested JSON object at all of its levels. It seems I should be using more 'dot notation' on both the server and client sides to access the nested level in the JSON, but I can't seem to find a wining combination.
UPDATE Here's where I'm at with incorporating @fabrv suggestions.
Nesting ul/li Tags The original ask is using a form and select/option tags, but I thought I'd try a poc with ul/li tags.
<ul style="list-style-type: none;">
<% iosUberList.forEach(function(parent){ %>
<li>
<span>Level 1: <%- parent.iosUber.name %></span><br><br>
<% parent.iosUber.has_campbus.forEach(function(campbus){ %>
<span>Level 2: <%- campbus.name %></span><br><br>
<% campbus.has_schcolunit.forEach(function(unit){ %>
<span>Level 3: <%- unit.name %></span><br><br>
<% unit.has_dept.forEach(function(dept){ %>
<span>Level 4: <%- dept.name %></span><br><br>
<% }) %>
<% }) %>
<% }) %>
</li>
<% }) %>
</ul>
ul Tag Result
Level 1: UofO
Level 2: AAA Campus
Level 3: AAA School College Unit 1
Level 4: AAA Department 1
Level 4: AAA Department 9
Level 3: AAA School College Unit 2
Level 4: AAA Department 10
Level 4: AAA Department 2
Level 2: BBB Campus
Level 3: BBB School College Unit 3
Level 4: BBB Department 11
Level 4: BBB Department 3
Level 3: BBB School College Unit 4
Level 4: BBB Department 12
Level 4: BBB Department 4
Level 2: CCC Campus
Level 3: CCC School College Unit 7
Level 4: CCC Department 7
Level 4: CCC Department 15
Level 3: CCC School College Unit 8
Level 4: CCC Department 8
Level 4: CCC Department 16
Level 2: DDD Campus
Level 3: DDD School College Unit 5
Level 4: DDD Department 5
Level 4: DDD Department 13
Level 3: DDD School College Unit 6
Level 4: DDD Department 6
Level 4: DDD Department 14
Nesting select/option Tags This is what I'm trying to accomplish but the nesting/dot.notation is not working as expected. I can get it to function as expected by nesting level 2 inside level 1, but as soon as I nest level 3 inside level 2 it falls apart. Note that I'm not using a select/option for the top/parent level since there's only 1 thing (no multi to choose from).
<span>Level 1</span><br>
<% iosUberList.forEach(function(parent){ %>
<span><%= parent.iosUber.name %></span><br><br>
<form>
<label>Level 2</label><br>
<select>
<% parent.iosUber.has_campbus.forEach(function(campbus){ %>
<option><%= campbus.name %></option>
<% }) %>
</select>
</form>
<% }) %>
If I stop here, I see
Level 1
UofO
Level 2
Dropdown containing |AAA Campus BBB Campus CCC Campus DDD Campus|
If I try to add Level 3,
<span>Level 1</span><br>
<% iosUberList.forEach(function(parent){ %>
<span><%= parent.iosUber.name %></span><br><br>
<form>
<label>Level 2</label><br>
<select>
<% parent.iosUber.has_campbus.forEach(function(campbus){ %>
<option><%= campbus.name %></option>
<label>Level 3</label><br>
<select>
<% campbus.has_schcolunit.forEach(function(unit){ %>
<option><%= unit.name %></option>
<% }) %>
</select>
<% }) %>
</select>
</form>
<% }) %>
I get chaos, what am I missing?
Many thanks for any help,
