If exists update column else create, but with tricky parts (I think)


If exists update column else create, but with tricky parts (I think)

it should still fix some issue Here's the deal: I'm creating a rails RESTful API for storing information in a PostgreSQL database, and I'm using Parents and Childs controllers and Parent and Child models (example names).
code :
def update_previous_child
  conditions = {type: self.type, parent_id: self.parent_id}

  if existing_child = Child.find_by(conditions) # or Child.where(conditions).last
    new_value = (existing_child.value || []) + [new_hash]
    existing_child.update_attribute(:value, new_value)
  end
end
def update_previous_children
  conditions = {type: self.type, parent_id: self.parent_id}

  Child.where(conditions).each do |existing_child|
    new_value = (existing_child.value || []) + [new_hash]
    existing_child.update_attribute(:value, new_value)
  end
end

Hope this helps You can use list comprehension with str.contains and concat with cast to int for 0,1 DataFrame:
code :
L = [df['text'].str.contains(x) for x in glossary]
df1 = pd.concat(L, axis=1, keys=glossary).astype(int)
print (df1)
   phrase 1  phrase 2  phrase 3
0         1         1         0
1         1         0         0
2         0         0         1
3         1         1         1
df = df.join(df1)
print (df)
                                    text  phrase 1  phrase 2  phrase 3
0        This is a phrase 1 and phrase 2         1         1         0
1                               phrase 1         1         0         0
2                               phrase 3         0         0         1
3  phrase 1 & phrase 2. phrase 3 as well         1         1         1
Update whole or parts of column in a single row on MySQL and Nodejs

Update whole or parts of column in a single row on MySQL and Nodejs

Does that help I am having trouble with querying whole or parts of the column in a single row. I am creating a form that can both create (post) and edit(put) data into the form. , This is the correct way to perform a MySQL query update using Nodejs
code :
exports.putProduct = router.put("/api/product/update/:id", (req, res) => {
  const putData = req.body;
  const idToPutData = req.params.id;
  mySQL.query(
    "UPDATE `product` SET `category`=?, `productname`=?, `os`=?, `model`=?, `serialnumber`=?, `price`=?, `equipment_condition`=?, `detail`=?, `image`=? WHERE id=?",
    [putData.category, putData.productname, putData.os, putData.model, putData.serialnumber, putData.price, putData.equipment_condition, putData.detail, putData.image, idToPutData],
    (err, results, fields) => {
      if (err) console.log(err);
      res.end(JSON.stringify(results));
    }
  );
});

like below fixes the issue I have a dataframe like this: , Here is one way findall
code :
df['label'] = df.comment.str.findall('|'.join(['cat','dog'])).str[0]
Out[10]: 
0    dog
1    dog
2    cat
3    NaN
Name: comment, dtype: object
r='(cat|dog)'
df['label'] = df.comment.str.extract(r)

this will help From your query, since you're doing .updateMany(), you don't have to do { multi: true }. Anyway usually you can do upsert using {upset: true}, but it would ideally create a new document based on filter criteria with update fields from input query only if no match is found in DB. But since here we're have a list ($in) in filter criteria it might not work normally, try this :
code :
let winnerLeads = [1, 2, 3, 31, 5]
let groupTarget = 1
let howManyClaims = 2
let bulkArr = []
for (i of winnerLeads) {
    bulkArr.push({
        updateOne: {
            "filter": {
                LeadId: i,
                TargetedToBeClaimedByClientType: groupTarget
            },
            // If you wanted it to be incremented rather than replace the field, then try `$inc` instead of `$set`.
            "update": { $set: { TotalClaimsToBeClaimedByClientType: howManyClaims } },
            "upsert": true
        }
    })
}
db.EightWeekGamePlan.bulkWrite(bulkArr);
