adding data to firebase realtime database from an object (web)












0















I have an object containing multiple key value pairs, I want to add all the keys and their values, from inside the object to an existing node, without disturbing the data already present inside the node.



If i write like this



var ref = firebase.database().ref("hams/spam_words/");

ref.update({

new_words_ham //new_word_ham is an object containing n number of words

});


it will add new_words_ham as another child node inside the main node , i cannot have that



even using a forloop on the object does not work



var ref = firebase.database().ref("hams/spam_words/");
for(var i in new_words_ham){
var word = i
ref.update({
i
});


I am new to js as well as to firebase. Please do tell me if i have got any concept wrong

  • This statement looks a bit strange ref.update({ new_words_ham }); Are the wrapping curly brackets a typo or is removing them solving your problem?

    @DennisAlund modern JavaScript allows { new_words_ham } as a shorthand for { new_words_ham: new_words_ham } . Yes, I find it incredibly hard to get used to too. ;-)

Your existing code



//new_word_ham is an object containing n number of words
firebase.database().ref("hams/spam_words/").update({
new_words_ham
});


Can be rewritten as



firebase.database().ref("hams/spam_words/").update({   
new_words_ham: new_words_ham
});


when the shorthand syntax is expanded. What I believe you want is simply



firebase.database().ref("hams/spam_words/").update(new_words_ham);
